Java Model Exception: Error in Java Model (code 969): src/main/.... [in app] does not exist

[mikehaertl]

I try to work on a foreign Android project in neovim + nvim-jdtls and get unexpected errors in this form when eclipse.jdt.ls starts:

Java Model Exception: Error in Java Model (code 969): src/main/java/com/xxxxxlog/app/domain/ihm [in app] does not exist

But that path exists and contains class files.

Full log output:

Sidenote: That other error (Cannot download Gradle sha256 checksum) seems to not be a problem. I also have it on another project but the LSP features work fine there. I just don't get why it tries to fetch the checksum for gradle 8.9 because the project uses gradle 8.6. There's no 8.9 configured anywhere.

[mikehaertl]

Related to / potential duplicate of #3046?

@rgrunber Different to your issue I'm able to reproduce this error everytime. Is there anything else I can provide to help fixing the problem?

[rgrunber]

It's probably a separate issue from #3046. Java model errors are a general type of error.

Are you able to share your project ? Do you know what version of JDT-LS is being used with the client ?

[mikehaertl]

Unfortunately it's a private code base.

jdtls is v1.35.0.

[rgrunber]

I think you're running a nightly version of JDT-LS. The version of gradle referenced is gradle-8.9-20240607003743+0000, which seems like it was built 2024-06-07, which we couldn't have shipped with our End of April release.

https://www.eclipse.org/downloads/download.php?file=/jdtls/snapshots/jdt-language-server-1.37.0-202406071833.tar.gz does contain the following metadata in the language server under gradle/checksums/versions.json :

{
  "version" : "8.9-20240607003743+0000",
  "buildTime" : "20240607003743+0000",
  "current" : false,
  "snapshot" : true,
  "nightly" : true,
  "releaseNightly" : false,
  "activeRc" : false,
  "rcFor" : "",
  "milestoneFor" : "",
  "broken" : false,
  "downloadUrl" : "https://services.gradle.org/distributions-snapshots/gradle-8.9-20240607003743+0000-bin.zip",
  "checksumUrl" : "https://services.gradle.org/distributions-snapshots/gradle-8.9-20240607003743+0000-bin.zip.sha256",
  "wrapperChecksumUrl" : "https://services.gradle.org/distributions-snapshots/gradle-8.9-20240607003743+0000-wrapper.jar.sha256"
}

I'm not sure why it attempted to fetch that instead of using the wrapper that's listed in the project, but it could be an issue in validating the gradle wrapper. We do check that the version of Gradle listed matches exactly the checksum of the proper released version.

It might be worth trying JDT-LS 1.36 or something else just to see if that works.

[mikehaertl]

That's weird. I've installed jdtls via mason-nvim. It clearly references the 1.35 download as can be seen in it's registry file here:

https://github.com/mason-org/mason-registry/blob/8ae81b2226c0ebe27fcf433397ebd7ecca24aa9c/packages/jdtls/package.yaml

[rgrunber]

Have a look from #2898 (comment) and below . Very similar issue. I had the user report the output of jps -lv to confirm the version and it wasn't what they expected.

[mikehaertl]

Here's the output of jps -lv. Note that I work on several Java projects in parallel each with different gradle versions.

I've now also tried with 1.36 and still get the same errors:

Having checked how the checksums are verified, I don't think the download failure is harmful. With that said, could you check for the presence of /home/mike/.cache/tooling/gradle/ and remove the contents of that directory. It should just include a checksums/ folder and a versions.json file. Then try to re-import the project and see if you still get that Gradle error.

[mikehaertl]

I removed the content from that directory and now the gradle error is really gone, thanks.

But the main problem is still there:

Java Model Exception: Error in Java Model (code 969): src/main/java/com/xxxxxxlog/app/ui/screens/ihm/addresult [in app] does not exist

[archer-n]

I have the same problem and can reproduce this issue using https://github.com/eclipse-jdtls/eclipse.jdt.ls/tree/master/org.eclipse.jdt.ls.tests/projects/gradle/android

My environment:

jdtls: jdt-language-server-1.37.0-202406130424.tar.gz
jdk: openjdk 17.0.11 2024-04-16

Here is my initialization configuration:

[jdneo]

Have you set java.jdt.ls.androidSupport.enabled to on?

[mikehaertl]

I've added that setting now but no difference. Still see that exception in jdt.ls logs and the LSP does not work properly.

[mikehaertl]

I had similar errors in other (non-android) projects (... is not on the classpath ...). I found that buildWorkspace (:JdtlsCompile in nvim-jdtls) fixed it there. Looking at .classpath it makes sense. That file references the bin/ directory:

<classpathentry kind="output" path="bin/default"/>

Calling buildWorkspace actually populated the bin/ directory in the other project. Not sure why this had to be triggered manually, though.

So I tried the same for this android project. The buildWorkspace command reports success but there is no bin/ directory created.

So the error remains.
