Android Studio 0.8 - No longer runs custom tasks

Question

I have just upgraded from Android Studio 0.6 to 0.8.3 (on Linux Mint 15) and now my build is not working as expected. In my gradle file I have lots of custom Tasks which do prebuild steps (copying files, resizing images, etc).

// lots of tasks snipped  
task convertToOGG(type:Exec) {
    ext.srcDir = 'bb/src/main/buildAssets/wavs/'
    ext.destDir = 'bb/src/main/res/raw/'
    workingDir '..'
    commandLine 'python', 'scripts/convertToOGG.py', srcDir, destDir
}

gradle.projectsEvaluated {
    copyRes.dependsOn resizeImageIcon
    convertToOGG.dependsOn copyRes

    preBuild.dependsOn copyRes, convertToOGG
}

These don't run by default in the IDE any more. They are dependencies of the preBuild step, but don't run if I manually run the preBuild step in the IDE:

Its like the gradle.projectsEvaluated block is no longer run. Strangely if I run it in a terminal it works:

Can anyone help? Thanks

I fixed it by changing:

gradle.projectsEvaluated {
    copyRes.dependsOn resizeImageIcon
    convertToOGG.dependsOn copyRes

    preBuild.dependsOn copyRes, convertToOGG
}

to

copyRes.dependsOn resizeImageIcon
convertToOGG.dependsOn copyRes

preBuild.dependsOn copyRes, convertToOGG
