== すべてのダウンロードオプション ==#Moredownloadoptions
JOSMのチームは[/roadmap 毎月]、**テスト版**を[wikitr:/Releases リリース]します。
このテスト版では、MS WindowsおよびApple Macの亜種が作成されています。
josm.jnlpをクリックしてJOSMを起動すると、常に最新のテスト済みのバージョンが取得されます。 Java [wikitr:/InstallNotes#Webstart Web Start]はこの背後にあるメカニズムです。

[=#DevelopmentVersion]
[/log/josm/?verbose=on&limit=20 毎晩]ビルドシステムが**最新バージョン**を生成します。
これらのバージョンは重大なエラーが発生することがあります。しかし、ほとんどはうまくいきます。
最新版では、Web Startのバリアントも利用できます。

スクリプトを実行する際には、[/latest 最新]、[/tested テスト済み]、または[/version その両方]をチェックして、ダウンロード帯域幅を減らしてください。

** Strip translations **[=#Striptranslations]  \\
ダウンロードサイズが問題である場合、テストされたバージョンのより小さいファイルが利用可能です。英語のみを含むダウンロードの場合、[/josm-tested.jar?lang=en ?lang=en]をURLに追加します。To include one translation replace `en` with the [wikitr:/TracLanguages language code] you want (lowercase first character, supported languages only). You can further reduce the file size by stripping the signing information off with appending [/josm-tested.jar?lang=en&unsigned=1 ?unsigned=1].

== リポジトリ ==

=== openSUSE  ===#Opensuse
[=#openSUSE]
JOSMのテスト版は、Application:Geoリポジトリにあります。

最初にrootユーザーとしてyastに追加するか、リポジトリをzypperで追加します（URLのバージョンを使用しているバージョンに置き換えてください）:
{{{
zypper ar -f https://download.opensuse.org/repositories/Application:/Geo/openSUSE_15.0 Application:Geo
}}}

その後、''josm''と''josm-fonts''パッケージをインストールしてください。

=== Ubuntu ===#Ubuntu

このパッケージリポジトリはUbuntu用です。 他のDebianベースの（特にUbuntuベースの）ディストリビューションでも動作するはずですが、Ubuntu以外のディストリビューションではあまりテストやメンテナンスをしていません。

Ubuntuリポジトリには二つのパッケージが含まれています:
* ''josm'' - テスト版を提供します（安定版）。公式のUbuntuリポジトリからパッケージを置き換えます。
* ''josm-latest'' - 最新版(nightly)。josmパッケージと並行してインストールできます。デフォルトの設定フォルダは {{{~/.josm-latest}}} です。

以下で説明する通常の手順に加えて、古いDEBは[/apt/pool/universe/j/ アーカイブ]から手動でダウンロードできます。

==== インストール ====

パッケージリソースリスト {{{/etc/apt/sources.list}}} を編集してください:

{{{
#!sh
sudo editor /etc/apt/sources.list
}}}

利用中のUbuntuのバージョンに応じた行を追加してください:
 
{{{ 
#!sh
deb https://josm.openstreetmap.de/apt trusty universe
deb https://josm.openstreetmap.de/apt xenial universe
deb https://josm.openstreetmap.de/apt alldist universe
}}}

これに代えて、これは次の一行で行うことができます:
{{{
echo deb https://josm.openstreetmap.de/apt $(lsb_release -sc) universe | ↩
↪sudo tee /etc/apt/sources.list.d/josm.list > /dev/null
}}}

{{{#!comment 
### below did not work on all systems 
以下の行を追加してください:
`
deb https://josm.openstreetmap.de/apt VERSION universe
`
}}}

[[/josm-apt.key|公開鍵]]をダウンロードして登録してください:
{{{
#!sh
wget -q https://josm.openstreetmap.de/josm-apt.key -O- | sudo apt-key add -
}}}

ソースを更新します (`sudo apt-get install apt-transport-https`をインストールする必要があります)
{{{
#!sh
sudo apt-get update
}}}
インストールします

{{{
#!sh
# これらのパッケージが以前にインストールされていない場合は、この最初の行をスキップできます。
sudo apt-get remove josm josm-plugins

# テスト済み版の場合
sudo apt-get install josm
# 開発版の場合
sudo apt-get install josm-latest
}}}

== トラブルシューティング ==
=== Java ===#Java
[=#Doubleclickonafiledoesnothing When you double-click on a jar file and nothing happens] in most cases this means Java isn't installed.

JOSM is tested with Oracles variant, so we recommend to get Java from their pages for [https://www.java.com/download/manual.jsp manual] downloads or [http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html intermediate] versions. But first give the Java already distributed with the operating system a try, [https://en.wikipedia.org/wiki/OpenJDK for example].

When choosing a download keep in mind:
 * A Java Plug-in for web browsers is **not** needed to run JOSM. Therefore results from pages like www.java.com/en/download/installed8.jsp are not relevant.
 * A Java variant with 64 bit is recommended for JOSM. The operating systems architecture is important for deciding between 32 bit Java or 64 bit Java. Because JOSM is **not** affected by the web browsers architecture most recommendations on this page www.java.com/en/download/faq/java_win64bit.xml are not relevant.
 * Avoid pages like www.java.com/en/download which intent to place Java Plug-ins in web browsers. And this is **not** important for JOSM.

For further information visit the [InstallNotes Installation Notes] and [https://www.java.com/en/download/help/troubleshoot_java.xml troubleshooting] pages.
''Java'' in this section means a JRE (Java Runtime Engine) which provides a JVM (Java Virtual Machine) to run JOSM, a Java program that is developed using JDK (Java Development Kit) and sometimes launched with the JNLP (Java Network Launch Protocol aka Web Start and successor of Java Plug-ins).

==== Testing Java ====#Javatest
[=#Troubleshootingjarfile] Checks if Java is installed and why JOSM does not start (example mainly for MS Windows).
1. Download [/josm-tested.jar josm-tested.jar] to your desktop.
1. Open a Command Prompt aka Terminal
1. Type `cd %homepath%`? and type `cd Desktop`?
1. Type `java -version `? Three lines with the version data should appear. If you see something else then Java is not properly installed.
1. Type `java -jar josm-tested.jar`?. Now JOSM should run, started from the [wikitr:/Help/CommandLineOptions Command Line].
1. Quit JOSM.
1. Type `josm-tested.jar`?. If JOSM starts again, the Windows Explorer is ready for double clicks on jar files.

=== Web Start ===#Webstart
[=#Troubleshootingjhlplink]
Launching JOSM via Web Start has many more error causes than the traditional way with first downloading a jar file and afterwards starting it.
So please test [#JavaTest Java] first and then run the tests described below or elsewhere [https://www.java.com/en/download/faq/java_webstart.xml Web Start issues].

==== Testing Web Start ====#Webstarttest
1. Download [/josm-tested.jar josm.jnlp] to your desktop.
1. Open a Terminal and move to the Desktop as above
1. Type `javaws josm.jnlp`?. This should initially download JOSM, serve a security dialog and then launch JOSM.

=== Virtual Machine ===#Troubleshootingjvm

==== メモリ不足 ====

Nowadays manually controlling Javas memory is seldom needed because available RAM on computers has grown.
Wrongly chosen values can decrease JOSM performance.

For some tasks, JOSM has a large appetite for memory. On the one hand, it may be necessary to configure a memory size that supports more plugins and features. On the other hand can slow machines be stabilized by restricting Javas memory use.
If needed, use the [wikitr:Help/CommandLineOptions command line] to set the [https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html#BABHDABI Java Option] -Xmx…m, for example `-Xmx512m` or `-Xmx1536m`.
Formerly older java programs accepted `-Xmx=512m` or even `-Xmx 512m`. Now those malformed arguments throw error messages.

==== VM選択 ====#VMselectiononWindowsx64

On current versions of MS Windows by default Java is installed mainly in the `C:\Program Files\Java\` directory. Additional parts are placed in `C:\Program Files\Oracle\Java\`. There is a `.\javapath\` directory as target for the PATH environment variable. It is the home for the three virtual files `java.exe`, `javaw.exe` and `javaws.exe`. This files are symbolic links form the current Java installations.

On older versions of 64 bit Windows sometimes the 32 bit mode JRE was additionally installed.  Also some browsers brought their own JVM with limited capabilities. In those cases a Web Start from the browser would not use your Java installation but that from the browser.

Check that there's no other javawebstart in {{{\Windows\SysWow64}}}. The Java control panel will not detect it and you can safely delete it. Perfom cleanup and only keep the latest versions of each JRE (One or the 32-bit mode, another one for the 64-bit mode).

For shortcuts created on the desktop for JNLP and running the Javawebstart launcher , make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "{{{-d64}}}" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!)

Example of an edited command line for a shortcut on the windows desktop:
{{{
#!sh
javaws.exe -J-d64 -J-Xmx2048m  josm.jnlp
}}}

=== Windows josm.exe ===#Mswindowswrapper

Using josm-setup.exe for installation on Microsoft Windows does the following:
 * Puts the files `josm-tested.jar` and `josm.exe` in directory chosen by the user, default is `C:\Program Files (86)\JOSM\`
 * Suggests to register josm.exe as target for the file extensions `*.osm` and `*.gpx`.
 * Suggests to place JOSM shortcut icons on the Desktop and in the Start Menu (Currently they are placed for an admin only and can be copied from there, #11398).
 * Asks if the Plug-Ins Imagery offset database and Turn restrictions should be provided.
 * Adds uninstall data at the appropriate places.

When starting, josm.exe searches its directory for the jar file and runs the command `\path\to\javaw.exe -Xms128m -Xmx1024m -jar \path\to\josm-tested.jar`.
Josm.exe acts as a ''wrapper'' and is [wikitr:/USB_Stick portable].

When josm.exe finds the argument `--l4j-debug`, it writes the log file `launch4j.log` into the current directory if that is writeable. Some other [http://launch4j.sourceforge.net/docs.html#Runtime_options options] are possible and all usual [wikitr:/Help/CommandLineOptions#Programarguments JOSM Program arguments] too. See example:

{{{
#!sh
# Write a log while starting JOSM and load OSM data
josm.exe --l4j-debug https://www.osm.org/way/476702262
}}}

For giving [wikitr:Help/CommandLineOptions#Javaoptions Java options] to the Java VM josm.exe uses the optional file `josm.l4j.ini` in its directory. In this file each option needs a separate line and comments are possible, see [http://launch4j.sourceforge.net/docs.html#Additional_jvm_options Additional JVM options].

While being a 32-bit program, josm.exe seems to need a 64-bit Java on 64-bit Windows.

=== MacOS でのエラー ===#Macoserrors
[=#MacOSErrors][=#MacOSXMountainLionErrors]
{{{
#!comment

}}}

Apple has two mechanisms to ''protect'' you from using JOSM: [https://support.apple.com//HT201940 File Quarantine] and [https://support.apple.com//HT202491 Gatekeeper].

==== Downloaded from the internet ====
If you get an error saying "'JOSM.app' is an application downloaded from the internet." you can bypass this by **right-clicking on JOSM.app** or josm.jnlp and selecting 'open'. You should then see the same message but this time with an option to "Open" regardless. This is only necessary on the first run of JOSM.

==== Damaged ====
[[Image(#8787:damaged_josm_app.png,width=300,align=left,margin-top=-50,margin-right=30)]]

If you get an error saying "'JOSM.app' is damaged and can't be opened. You should move it to the Trash", then you need to temporarily disable Gatekeeper.

Open System Preferences and the 'Security & Privacy' options. Set 'Allow applications downloaded from:' to 'Anywhere'.

[[Image(wiki:Download:SecurityPrivacy.png,align=right,float=left,width=300)]]

If that radio button is missing from the Security & Privacy preferences panel, open the Terminal window. The following command may become the radio button to appear.

{{{
sudo spctl --master-disable
}}}

==== Using brew ====#brew
MacOS users may choose [https://brew.sh/ homebrew] package manager as a universal way to install and update their JOSM instance.

Using `brew cask` eliminates most of the above-mentioned issues. (see. [https://caskroom.github.io/]).

Open Terminal and run the next commands to install or upgrade JOSM to the current tested version, respectively:

{{{
brew cask install josm
}}}
{{{
brew cask upgrade josm
}}}
