Why are dependencies missing after gradle import in eclipse kepler

Question

I have imported the project JCPABE ( https://github.com/TU-Berlin-SNET/JCPABE ) via Buildship Gradle Integration in eclipse Kepler on Windows 10.

Now, many packages show me similiar errors, concerning 5-10 classes that are not existing, seems like they all are belonging to the package cpabe.policyparser. This package exists, but seems to lack certain java classes.

It seems like they are declared in gradle.build correctly, e.g.

compileJavacc {
    inputDirectory = compileJjtree.outputDirectory
    outputDirectory = file('generated/javacc/cpabe/policyparser')
}

But I cant find them in my project or the project or the workspace folder. How can I include them?

Missing classes are for example

Node
ParseException
ASTStart
TokenMgrError
ParseTree

There are I believe 2 ways to refresh your IDE classpaths.

Not yet ideal is to try to refresh the project using the plugin which you are using for Gradle integration I believe its Buildship (not sure I use IntelliJ)

Another solution to get this working without any IDE plugins is to apply plugin: eclipse in your build.gradle and just run gradle eclipse task to regenerate the classpaths.

you may also wish to add the generated folder to your sourceSets{} in your script.

sourceSets.main {
        java {
            srcDirs = [
                    "$projectDir/src/main/java",
                    "$projectDir/<path_to_your_generated_dir>",
            ]
            include '**/*.java'
        }
}
