Change in pure Java dependency does not cause GWT project to recompile

[dhoskins]

I have a project with two subprojects: GWT and Core. Core is a pure Java project which GWT relies upon. The GWT build.gradle looks like this:

apply plugin: 'gwt-compiler'
buildscript {
    repositories {
        jcenter() //repository where to fetch gwt gradle plugin
    }

    dependencies {
        classpath 'de.richsource.gradle.plugins:gwt-gradle-plugin:0.6'
    }
}

dependencies {
    compile project(':core')
    ... other dependencies ....
}

gwt {
    modules <myModuleName>
}

This builds fine, however does not recompile when I make a change to the Core project. The core jar rebuilds as expected, the GWT tasks all report "UP-TO-DATE".

I have tried adding src += files(project(':core').sourceSets.main.allJava.srcDirs) to the gwt component but this does not help either.

Same bug here.

I have used the following workaround:
compileGwt.inputs.files(tasks.getByPath(":core:jar").outputs.files.getAsPath())
Basically, it adds the core jar as an input file dependency, this way, when a file in "core" is updated, the compileGwt recompiles afterwards.
