Access file in JUnit test in Gradle environment

Question

Right now I have got a Java library which has a test class. In that class I want to access some files located on my hard disk.

The build.gradle looks like this:

apply plugin: 'java'

dependencies {
    testCompile 'junit:junit:4.11'
}

My file is under java_lib/src/test/assets/file.xml and the Java class is under java_lib/src/test/java/<package_name>.java

Therefore I execute

final InputStream resourceAsStream = this.getClass().getResourceAsStream("assets/file.xml");

Unfortunately I get null back. What am I doing wrong?

To get thing rolling you need to add the following to the gradle file:

task copyTestResources(type: Copy) {
    from "${projectDir}/src/test/resources"
    into "${buildDir}/classes/test"
}
processTestResources.dependsOn copyTestResources

What it basically does is copying all the files in the src/test/resource directory to build/classes/test, since this.getClass().getClassLoader().getResourceAsStream(".") points to build/classes/test.

The issue is already known to Google and they want to fix it in Android Studio 1.2 (since they need IntelliJ14 for that and it seems like it will be included in Android Studio 1.2)
