Failure to compile plugin which worked flawless before

[stoecker]

I have a private plugin which compiled fine before. After the many changes in the build system now it fails in the build process.

compile:
     [echo] compiling sources for xyz.jar ...
    [javac] Compiling 18 source files to xyz/build
    [javac] warning: [options] bootstrap class path not set in conjunction with -source 8
    [javac] xyz/Barefoot.java:1: error: An unhandled exception was thrown by the Error Prone static analysis plugin.

Actually I don't need any errorprone checks, I only want to compile my plugin as before.

• Is there a way to fix this error?
• Is there a way to disable this, so that it compiles without these failing step?

[taylor.smock]

There should be a way to disable checks. I've turned off various errorprone checks in gradle, using something like this:

tasks.withType(JavaCompile).configureEach {
  options.errorprone {
    if ((JavaVersion.current().majorVersion as Integer) > 11) {
      check('Finally', CheckSeverity.OFF)
    }
  }
}

I don't know how to do that with a build.xml/ant file.

[simon04]

You're using build-common.xml? Have you updated also the 00_core_tools/ directory?

The error prone compiler is not yet resolved via Apache Ivy. Error prone has been added a long time ago and updated in [o34620] for Java 12. AutoValue has been added as a separate JAR in [o35342].

[stoecker]

Thanks for asking the right questions. Works now. Everything was updated, except the build-common.xml, as it must be modified for the paths and because it's a single file. Did that now and readded the necessary modifications.

Seems new core tools and old build-common.xml didn't like each other.
