Gradle second build fails after changing styles.xml

Question

I migrated the project to use Gradle (using the old Android project structure). I recently upgraded Android Studio to version 2.0, which forced me to use the android Gradle v0.5 plugin. I can build my project using any of the options that I defined, or during debugging / release.

Something went wrong for me using the following script:

• Perform cooling towing
• Run an engraving assembleTestenvDebug
• Gradle output:

CREATE SUCCESSFULLY

• Change any value in styles.xml
• Engrave assembleTestenvDebug (again)
• Gradle output:

/Users/myuser/Project/src/com/namespace/project/views/SomeCustomView.java:60: error: could not find the character mSize = arr.getInt (R.styleable.SomeCustomView_some_custom_styleable, 0);

Gradle now complains about every custom xml attribute that I declared in attrs.xml. It drives me crazy, as I have to clean and rebuild the project every time I change styles.xml

Please help me.

Thanks!

build.gradle in the project directory:

and build.gradle for each of the library projects:

Answer 1

This is fixed in 0.5.4, which is available now.

Answer 2

I have a theory, but I could be wrong.

Looking for a user guide I do not see any mention of adding custom source sets directly. This may mean that the build system does not detect changes to sourceSets, such as testenv , unless it is part of the taste or type of build.

I would try to define your environment as a group of taste. Not sure about your specific requirements, but it might look something like this:

 flavorGroups "environment", "flavors" productFlavors { testenv { flavorGroup "environment" } prodenv { flavorGroup "environment" } flavorA { flavorGroup "flavors" ... } flavorB { flavorGroup "flavors" ... } 

This suggests that you need an assembly that may consist of these two, for example app-flavor1-testenv-debug.apk . Just a thought though, I did not test it.

Also, if you get this working, I would recommend switching to a new layout. So you can rely on the src/main/res conventions merging with src/testenv/res and src/debug/res if they exist, without even mentioning them in build.gradle .
