Exclude unchanged classes and methods from HTML report #355

Closed NotMyFault closed 1 year ago

NotMyFault commented 1 year ago

Hey,

I'm using the --html-file file option to generate an HTML report. Would it be possible to skip unchanged classes? I'm looking for a way to generate a report that covers changed contents only, I don't need to document everything that didn't change. The -m option reports a few unchanged classes still.

Thanks in advance!

Have you tried onlyBinaryIncompatible and onlyModified (see here)?

I tried command java -jar japicmp-0.17.3-SNAPSHOT-jar-with-dependencies.jar -n /home/dc-user/software/jdk8u362-b09/jre/lib/rt.jar -o /home/dc-user/software/zulu8.72.0.17-ca-jdk8.0.382-l_x64/jre/lib/rt.jar --html-file /home/dc-user/software/report.html

it runs forever. if I remove html option, it will output directly.

anything I'm wrong to generate html report?

@kayhong: I guess you need to increase heap space for the java process. If there is not much memory available, the jvm needs to do a lot of garbage collection that costs time. On my machine I have run it that way:

java -Xms4g -Xmx4g -jar target/japicmp-0.17.2-SNAPSHOT-jar-with-dependencies.jar -o /opt/java/jdk1.8.0_321/jre/lib/rt.jar -n /opt/java/jdk1.8.0_321/jre/lib/rt.jar --ignore-missing-classes --html-file report.html

That was it, thanks!
