Proguard keep by source file path

Proguard has options for -keep-ing a class based on its package name/hierarchy.

Is it possible to -keep based on the source file's actual path?

Example:

java/com/a/b/c/Class.java contains package com.a.b.c.Class tests/com/a/b/c/ClassTest.java contains package com.a.b.c.ClassTest

There may be a large number of "*Test" classes and I want to Proguard -keep everything under tests/* for testing purposes. It should not keep any classes which happen to match "*Test" outside of the tests/* directory.

It doesn't seem like this would be possible with package matching since it has the same package as those classes under java/*

Solution

  • No, this is not possible. ProGuard does not consider the file path when applying rules.

    You could use annotations for your test classes, e.g.

    @TestClass
public class MyTest {
   ...
}

    and then add a configuration like this:

    -keep @TestClass class * { *; }
