I am very sorry @cpovirk but the Gradle Metadata just published is broken. If you look at these two files:

• https://repo1.maven.org/maven2/com/google/guava/guava/32.1.0-jre/guava-32.1.0-jre.module
• https://repo1.maven.org/maven2/com/google/guava/guava/32.1.0-android/guava-32.1.0-android.module

You see several versions like HEAD-android-SNAPSHOT in them.

I believe this is because the util/set_version.sh script was not used to set the version here.
My assumption was that this is somehow automatically used before each release. So I did not think about that further. I guess I was wrong and that's not the case. 😞

These lines need to be executed on a version change:
https://github.com/google/guava/blob/master/util/set_version.sh#L18-L21

I am afraid this requires patching, as in certain situations the metadata now points at files not available on Maven Central.
