配置可用插件。
首选项对话框的此寄存器有两个选项卡，用于 安装插件 和配置策略 自动更新。

插件可以扩展 JOSM 的核心功能。 列表 Plugins for JOSM (en) 显示了官方插件及其功能类型。 用户安装一些插件是很常见的。

==安装插件==#Plugins

1. （可选）单击 下载列表 以下载可用插件列表（如果未显示任何内容）。
2. （可选）使用顶部的复选框和搜索文本字段来过滤列表。
3. 勾选您要安装的每个插件的复选框。
4. 单击确定。

JOSM 将下载并安装插件。
有些插件需要重新启动 JOSM 才能完全安装。 如果需要，将会出现确认信息。

请仅安装您需要的插件。 插件可能会增加代码错误的可能性，某些组合甚至可能未经测试。 由于插件可能是来自“互联网某处”的文件，因此请牢记安全相关问题。

===手动安装=== 如果确实需要手动安装，您可以将 .jar 文件放在 JOSM user-data (en) 目录下的 plugins 目录中。 现在重新启动，插件应该显示在插件列表中。 勾选这些手动放置的插件的复选框以最终安装它们。

插件更新策略

更新插件

图片(自动更新.png,link=,右,margin-left=10,margin-bottom=10) 启动时，JOSM 尝试更新插件

• 如果自上次插件更新以来 JOSM 本身已更新。这称为基于版本的更新模式。
• 如果自上次插件更新以来已经过去了一段时间。这称为基于时间的更新模式。

在这两种情况下，JOSM 都会提供更新当前活动插件的功能，建议您通过单击“更新插件”来运行更新。您也可以跳过更新，但请注意，已安装的插件可能与新的 JOSM 版本不兼容，并且它们可能无法加载或无法按预期工作。

如果 JOSM 应始终尝试所选操作而不要求确认，请选择“不再询问并记住我的决定”。如果您选择此复选框，JOSM 将不再显示此对话框。

选项

图片(plugin_update_policy_preferences.png,link=,右,,margin-left=20,margin-bottom=10)

• 如果 JOSM 在版本和/或基于时间的更新模式下更新插件之前询问，请选择单选按钮更新前询问。
• 选择单选按钮 始终更新而不询问 JOSM 是否应自动更新插件而不询问。
• 选择单选按钮从不更新以禁用版本或基于时间的自动更新。如果选择此策略，JOSM 将在启动时跳过自动更新。

基于时间的更新模式的间隔天数可以在单选按钮下方设置（“默认=30”）。

注意： 如果插件在启动时更新，则不需要重新启动。

手动更新插件

1. 启动 首选项 对话框。
2. 选择选项卡 插件。
3. 点击 下载列表，下载可用插件列表。
4. 您安装的插件已在复选框中选中
5. 单击 更新插件。

JOSM 将更新选定的插件。您必须 restart (en) JOSM 才能完成更新过程。

Preferences > Plugins

Configure available plugins.
This register of the Preferences dialog has two tabs to install plugins and to configure the policy automatic updates.

Plugins can extend the core functionality of JOSM. The list Plugins for JOSM (en) shows the official plugins and their kinds of functionality. It is common that users install some plugins.

Installing plugins

1. (Optionally) Click on Download list to download the list of available plugins (if nothing was shown).
2. (Optionally) Use the checkboxes and the Search text field on top to filter the list.
3. Tick the checkbox for every plugin you want to install.
4. Click on OK.

JOSM will download and install the plugins.
Some plugins require a restart of JOSM to get fully installed. A confirmation will appear if needed.

Filter by text	Plugin list	Filter by status
Reload list data from server	Update the selected plugins manually	Only visible in Expert mode (en)

Please, install only the plugins you need. Plugins will probably rise the chance of code errors and some combinations might even not been tested. As a plugin could be a file from Somewhere in the Internet keep the security related issues in mind.

Manual installation

If a manual installation is really needed, you can put the .jar files in the plugins directory under JOSM user-data (en) directory. Now restart and the plugins should show up in the plugin list. Tick the checkboxes of these manually placed plugins for finally installing them.

Plugin update policy

Updating plugins

On start-up, JOSM attempts to update the plugins

• if JOSM itself has been updated since the last plugin update. This is called the version based update mode.
• if a certain period of time has elapsed since the last plugin update. This is called the time based updated mode.

In both cases, JOSM offers to update the currently active plugins and you are advised to run the updates by clicking on Update plugins. You may also skip updating, but be warned, that installed plugins could be incompatible with the new JOSM version and that they might either fail to load or fail to work as expected.

Select Do not ask again and remember my decision if JOSM should always try the selected action without asking for confirmation. If you select this checkbox, JOSM won't display this dialog anymore.

Options

• Select the radio button Ask before updating if JOSM shall ask before updating plugins in version and/or time-based update mode.
• Select the radio button Always update without asking if JOSM shall automatically update plugins without asking.
• Select the radio button Never update to disable version or time based automatic update. JOSM will skip automatic update at startup if this policy is selected.

The interval in days for the time based updated mode can be set below the radio buttons (default=30).

Note: There will be not restart required if plugins are updated on start-up.

Manually updating plugins

1. Launch the Preferences dialog.
2. Select the tab Plugins.
3. Click on Download list to download the list of available plugins.
4. Your installed plugins are already selected at the checkboxes
5. Click on Update plugins.

JOSM will update the selected plugins. You have to restart (en) JOSM to complete the update process.
