jsweet-transpiler artifacts cannot be opened by ASM #663

Problem

When using recent jsweet-transpiler artifacts (versions 3.0.0, 3.1.0-SNAPSHOT) in Gradle 6.7.1 the ClassReader of ASM cannot read a class file in the JAR. After further investigation I figured that the JAR contains a Test.class file with invalid content.

Other Gradle versions are affected as well because Gradle/ASM is not failure tolerant to invalid class files.

* What went wrong:
Failed to create Jar file /Users/***/.gradle/caches/jars-8/117efba34acbd6ff63faa5dcc2adbd82/jsweet-transpiler-3.1.0-SNAPSHOT.jar.
> java.lang.IllegalArgumentException (no error message)

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.GradleException: Failed to create Jar file /Users/***/.gradle/caches/jars-8/117efba34acbd6ff63faa5dcc2adbd82/jsweet-transpiler-3.1.0-SNAPSHOT.jar.

Solution

The file in src/main/resources/Test.class must not be packaged in the transpiler JAR file.
