Add support for the Gradle Playframework plugin.#173
Merged
Conversation
Previously, the `index` command didn't work with Gradle projects that use the Playframework plugin. The codebase would compile, but no LSIF index would be created. Now, everything should work as expected. The problem was that the Playframework plugin uses the Scala plugin to compile auto-generated template and routes files. The Scala plugin runs Zinc (Scala incremental compiler) in a daemon process behind the scenes so it ignores the `javac` fork settings that `lsif-java index` adds to the build. The fix is to enable the SemanticDB Java agent on the Zinc daemon process and to add one more injection point to ensure that the SemanticDB compiler plugin is always on the classpath for all projects.
