Project with _tests_ breaks when used with a plugin combo of `war` and `liberty` with gradle.

Open hrsto opened this issue 5 years ago • 1 comments

A plain gradle webapp project with war plugin that has tests will completely break in vscode the moment the plugin id "io.openliberty.tools.gradle.Liberty" version "3.1-SNAPSHOT" is introduced into the build. Autocompletion dies, errors appear on every class there is in the main and test trees. If the plugin is removed, it goes back to normal. Alternatively, If the src/test folder is removed and liberty plugin kept, project goes back to normal.

From command line, everything is normal, project builds/tests without issues.

Environment

Operating System: Ubuntu 20.04.1 LTS
JDK version: 14 - Oracle and openjdk
Visual Studio Code version: latest
Java extension version: latest
With Gradle 6.6

Steps To Reproduce

Make a new gradle webapp project with the war plugin.
Add some plain junit test.
Introduce the io.openliberty.tools.gradle.Liberty to the build.
Everything breaks in vscode, but can run the build from command line (build, test, etc).
Remove the war and its place add java-library plugin and in vscode everything returns to normal.
Alternatively to 5, keep the war plugin and remove the src/test folder and in vscode everything return to normal.

Current Result

Attaching minimum sample. In build.gradle -> plugins can switch between the id 'java-library' and id 'war' plugins. When the war plugin is active, project breaks in vscode (errors on every class, no autocomplete) if there is src/test.

Try remove the src/test folder and it returns to normal.

Expected Result

Additional Informations

Tried cleaning all conceivable caches - gradle and vscode included. Ran it in a fresh VM as well with the same gradle/java combo. Affects local vscode development as well as the remote option (via ssh).

issue is still reproducible with the stock buildship-based gradle support, but goes away when using the gradle build server from vscode-gradle ( "java.gradle.buildServer.enabled": "on")
