Using Gradle and AspectJ with Android products that have their own source
I searched a lot but didn't see an answer to this. I have a source that comes in different flavors. Something like:
App/src/flavorA/MyFlavor.java App/src/flavorB/MyFlavor.java App/src/flavorC/MyFlavor.java
And it works fine until I need to run my AOP step. I found this was not possible because he could not find this class referenced by the source from App / src / main /.
This doesn't find the MyFlavor class:
android.applicationVariants.all { variant ->
variant.javaCompile.doLast {
def androidSdk = android.adbExe.parent + "/../platforms/" + project.ext.android_version + "/android.jar"
def iajcClasspath = configurations.compile.asPath + ";" + androidSdk
// This add project jars as well as support jars.
project.ext.tree = fileTree(dir: "${project.buildDir}/intermediates/exploded-aar", include: '**/*.jar')
project.ext.tree.each { jarFile ->
iajcClasspath += ":" + jarFile
}
ant.taskdef(resource: "org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties",
classpath: configurations.ajc.asPath)
ant.iajc(
source: "1.6",
target: "1.6",
destDir: "${project.buildDir}/intermediates/classes/${variant.dirName}",
fork: "true",
maxmem: "512m",
aspectPath: configurations.aspects.asPath,
inpath: configurations.ajInpath.asPath,
sourceRootCopyFilter: "**/.svn/*,**/*.java",
classpath: iajcClasspath
) {
sourceroots {
android.sourceSets.main.java.srcDirs.each {
pathelement(location: it.absolutePath)
}
pathelement(location: "${project.buildDir}/generated/source/r/${variant.dirName}")
pathelement(location: "${project.buildDir}/generated/source/buildConfig/${variant.dirName}")
}
}
}
}
I can get it to work if I add something like:
pathelement(location: "$`enter code here`{project.buildDir}/../src/flavorA/java")
But that's if I just want to create flavorA. Is there a better way to set it up so that when doing an IAJC task, it can find the source it needs for the specific variation it creates? If I build FlavorARelease my variant name will be something like flavorARelease and I can get the build type "release" by doing variant.buildType.name, but that won't help me. I need to point to the source for the scent I am creating.
I took variant.name and subtracted the assembly type name from it, which was left with the "flavorA" part:
pathelement(location: "${project.buildDir}/../src/${variant.name.substring(0, variant.name.length() - variant.buildType.name.length())}/java")
Still seems awkward. What if I want to collectRelease and build all flavors? There must be a better way to approach this which I cannot see.

You can iterate over the available options for your specific option using:
def currentFlavor;
variant.productFlavors.each { flavor ->
flavorToChoose = flavor
}
From here, you can take your desired flavor from the list and then add a path element similar to the "main" source, for example:
android.sourceSets."${flavorToChoose}".java.srcDirs.each {
pathelement(location: it.absolutePath)
}
Be sure to stick to this block in the sourceroots section.
