maven-shade-plugin

Customized version of maven-shade-plugin.

<groupId>org.immutables.tools</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>4</version>

1. Relocation with $ uglyfication

Allows class relocation patterns to contain $ sign. If pattern ends with $ sign, the dollar sign will be prepended in front of class names. This effectively prevents clashed during code completion.

<relocation>
  <pattern>com.google.common</pattern>
  <shadedPattern>com.my.internal.$guava$</shadedPattern>
</relocation>

The above pattern will result in ImmutableList being relocated as

com.my.internal.$guava$.collect.$ImmutableList

2. ServiceResourceTransformer that actually works properly

• Merges META-INF/services/* entries with deduplication of lines
• Applied class relocations to merged entries

3. Minimize Jar that works properly

• Does not remove used classes: fixed transitive class dependencies problem.
• Does not remove classes used in META-INF/services/* for used service types. Removes META-INF/services/* for unused service types. Explicitly include META-INF/services/** in filters to not delete such files and make all provider implementation types marked as non-removable.

I would love someone to contribute/reimplement those changes to the original Apache Maven maven-shade-plugin. I just couldn't afford time to dive into processes or infrastructure there.
