Module 'asm-renamed' now deploys to GitHub Packages

This means that instead of a system-scoped dependency we now have a
regular one.

The 'libx' module also downloads binary and source JARs redundantly into
the libraries directory in order to be found there by other scripts and
tests.

+  <name>ASM for AspectJ</name>
+  <description>
+    This module relocates the original ASM artifact from package name 'org.objectweb.asm' to 'aj.org.objectweb.asm',
+    using Maven Shade Plugin.
+
+    In order to avoid committing the binary to the AspectJ SCM repository and using it as a system-scoped dependency, we
+    deploy it to GitHub Packages.
+
+    Whenever it is necessary to upgrade to a new ASM version in order to make AspectJ compatible with a new Java
+    version, please build and deploy this module after upgrading property 'asm.version'. Make sure you have a GitHub
+    token with the necessary access rights and section like this in your settings.xml:
+
+    <![CDATA[
+    <server>
+      <id>github</id>
+      <username>MY_GITHUB_USER</username>
+      <password>MY_GITHUB_TOKEN</password>
+    </server>
+    ]]>
+
+    Then you should be able to run 'mvn clean deploy' for this module and be fine.
+
+    Caveat for IntelliJ IDEA: The project cannot be built in IDEA (Ctrl-F9) if this module is visible in the Maven view.
+    If so, right-click it and select "Unlink Maven Projects". Unfortunately, "Ignore Projects" is not enough. If Maven
+    knows of this Maven module, it cannot compile other modules depending on shaded class names, because it cannot find
+    the binaries. IDEA will just stop looking at the local Maven repository in this case.
