@portlek As you can see, all tests passed after adding 0778c4b.

@Goooler Sorry, but it doesn't work for me. am i doing something wrong here?

build.gradle.kts

relocate("a.b", "x.y.z.shade.a.b") {
    include("x/y/z/**/*")
}

Decompiled version of the jar:

package x.y.z;

import a.b.Example;
import a.b.c.Example;

---

@Test
fun testRelocateSourceWithExcludes() {
  // Main relocator with in-/excludes
  val relocator = SimpleRelocator(
    "org.apache.maven",
    "com.acme.maven"
  )
  relocator.include("foo.bar")
  relocator.include("zot.baz")
  relocator.exclude("irrelevant.exclude")
  relocator.exclude("org.apache.maven.exclude1")
  relocator.exclude("org.apache.maven.sub.exclude2")
  // Make sure not to replace variables 'io' and 'ioInput', package 'java.io'
  val ioRelocator = SimpleRelocator("io", "shaded.io")
  // Check corner case which was not working in PR #100
  val asmRelocator = SimpleRelocator("org.objectweb.asm", "aj.org.objectweb.asm")
  // Make sure not to replace 'foo' package by path-like 'shaded/foo'
  val fooRelocator = SimpleRelocator(
    "foo",
    "shaded.foo",
    excludes = listOf("foo.bar"),
  )
  assertThat(
    fooRelocator.applyToSourceContent(
      asmRelocator.applyToSourceContent(
        ioRelocator.applyToSourceContent(relocator.applyToSourceContent(sourceFile)),
      ),
    ),
  ).isEqualTo(relocatedFile)
}

this doesn't pass, i've just move include/excludes parameters to use the include/exclude methods. the reason i believe is that it calculates the sourcePackageExcludes and sourcePathExcludes on init, and when you add include/exclude after the creation of the simple relocator object it doesn't calculates that, and there is no way to create the relocator object with the include/exclude parameters as far as i know.

#1098 you can check this issue to see how to reproduce it and how it looks like in the code.
