"Projekt Java-EarlyAccess-Update-JDK" fails downloading Java with 404

[mdk]

The Jenkins Job "Projekt Java-EarlyAccess-Update-JDK" fails with 404 on downloading
https://download.java.net/java/early_access/jdk19/12/GPL/openjdk-19-ea+12_linux-x64_bin.tar.gz

[mdk]

And also "Java-EarlyAccess-JOSM" for Java19 is failing with

We cannot run Java, please ensure you have Java installed.
  We have tried to execute /opt/jdk-19/bin/java but failed.

Looking at the download page, the URL should be https://download.java.net/java/early_access/jdk19/19/GPL/openjdk-19-ea+19_linux-x64_bin.tar.gz.

This appears to be a problem with the script we use ( ​https://github.com/sormuras/bach/blob/master/install-jdk.sh -- we download this from ​https://raw.githubusercontent.com/sormuras/bach/master/install-jdk.sh ).

Looking at the tickets, ​bach/250, it looks like the master branch is intended to be deleted soon -- they also changed their default branch to main (like many other projects).

Furthermore, it looks like that script is no longer supported (see ​bach/248). It has been removed from their main branch.

So we should either (a) fork the script and update it ourselves, (b) switch to a different method of getting Java builds (in bach/250, ​jabba and ​sdkman were mentioned).

Of the two alternatives to the script, it looks like sdkman is better -- I'm not seeing any Java 19 releases from jabba remote-ls anyway.

Right now, I'm not particularly enamoured with sdkman either -- it isn't very script friendly. It would be doable, but unwise (IMO) to attempt to script it.

Examples with sdkman:

Java 18 GA

$ sdk install java 18-open

Java 19 EA

$ sdk install java $(sdk list java | awk -F'|' '/19/ && /open/ {print $6}' | head -n1)
Downloading: java 19.ea.19-open

In progress...

Repackaging Java 19.ea.19-open...

Done repackaging...

Installing: java 19.ea.19-open
Done installing!

Do you want java 19.ea.19-open to be set as default? (Y/n):

Interactive question! But this can be fixed with echo "sdkman_auto_answer=true" > ~/.sdkman/etc/config.

[taylor.smock]

I've taken a look at the script we use.

We pretty much have to change a few lines in ​https://github.com/sormuras/bach/blob/releases/11/install-jdk.properties:

install-jdk.properties

 # JDK 18

We'd also have to change the download link in ​https://github.com/sormuras/bach/blob/releases/11/install-jdk.sh for the properties file.

[stoecker]

Simply copy the stuff to our SVN and relink to it?

[stoecker]

Ah, I handled it locally on the server. Let's see...

[taylor.smock]

Replying to stoecker:

Simply copy the stuff to our SVN and relink to it?

Definitely an option. I'm OK with that, with the caveat that we're going to have to maintain it, and I had to (effectively) hand-edit the install-jdk.properties file.

It does look like there might be an ​automated way to update the properties file.

It looks like we'll want, at minimum:

• ​install-jdk.sh
• ​install-jdk.properties
• ​ShowJdkBuilds.java

[taylor.smock]

It looks like @stoecker fixed this in https://josm.openstreetmap.de/jenkins/job/Java-EarlyAccess-Update-JDK/1356/.

[mdk]

The same problem occurs again since 20.7.2022 while downloading https://download.java.net/java/early_access/jdk19/20/GPL/openjdk-19-ea+20_linux-x64_bin.tar.gz

[taylor.smock]

Yep. Rather unfortunately, both stoecker and Don-vip aren't very active right now (life happens), and only someone with server admin access can fix it, at this time. I think.

I believe stoecker copied the files I linked into the Jenkins instance, but it doesn't look like we are running the ShowJdkBuilds.java script automatically.

TBH, we should either put it in svn somewhere (either source:josm/trunk/scripts or someplace in source:osm/applications/editors/josm) or have it set up to run automatically when Java-EarlyAccess-Update-JDK fails.

[stoecker]

If you assign or CC me in tickets I'll see and react.

I updated the install-jdk.properties for Java 19 and Java 20 EA 10.

[stoecker]

Ok. I disabled Early access and switched Java 11 to Java 17 for JOSM and Plugins.

Remains to add java 20 and 21 and enabled these as well.

Ooops. Wrong ticket. See #23218
