ERROR: JAVA_HOME is set to an invalid directory: /snap/gradle/120/usr/lib/jvm/default-java

After upgrading to 120 (latest/stable, 7.2), I get

$ gradle                                          

ERROR: JAVA_HOME is set to an invalid directory: /snap/gradle/120/usr/lib/jvm/default-java

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

$ ls /snap/gradle/120/usr/lib/jvm/
java-1.16.0-openjdk-amd64  java-16-openjdk-amd64
$ echo $JAVA_HOME

Having the same issue. Since users can't rename files, the symbolic link for java-1.16.0-openjdk-amd64 should just need a rename to default-java, right?

I don't know why they left out a symbolic link to default-java 😞 Maybe we should create it ourselves?

The snap partition looks like is all read-only, if you want to write anything looks like you have to go through quite some commands :/

I actually meant to do it inside the PR. JDK for Gradle is bundled into the snap itself and JAVA_HOME points to the bundled JDK. At some point, upstream (or the distro maintainers) broke the symlink we had inside snapcraft.yml which causes this issue. We can either place the symlink back inside the snap or define an absolute path to the JDK directory like @dcap0 did in his PR.

18 should fix this. Please reopen otherwise.

[elect86]

When will we get the fix downstream?

@elect86 - it was actually present in edge channel but i just moved it into stable channel. please check.

[elect86]

I have no idea how to force/call an update on snap..

[elect86]

It looks like it's solved, thanks for fixing it
