Hi Marc, So carrying out the execution further... We are having long running tests. In our application we have configured jacoco:dump goal. we do have long running test as well.
Now we have migrated our project from jdk 8 to jdk 17. The Jacoco:dump goal is failing to start. The error is given in the very first mail. Additionally, We can not use other other like (report) because, the .exec which will get produced later is been read in Jenkins. And Now I am not able to figure out why agent is not even starting. What sort of thing is missing or misconfigured. Looking forward for your suggestions. Thanks & Regards On Friday, September 29, 2023 at 4:40:12 PM UTC+5:30 Marc R.
