How to optimize the compilation time when it takes too long?

[huangtao730]

I use the command "gradlew assemble" to compile, but it takes at least 20 minutes. It takes this long every time, and it takes even longer for the first compilation. How can I reduce this compilation time? It would be best if it can be compiled within 1 minute. I only need to compile this package "opentelemetry-java-instrumentation.jar"

After pulling the updates I ran ./gradlew assemble -x javadoc it took 4:25.28. Since there were changes to build scripts this was pretty much a full rebuild. You could try building with --scan and investigating the performance section in the build scan, perhaps that will reveal where the time is spent.
