Fail to read Exec JaCoCo file ANT
I am trying to generate an XML jacoco report from the generate exec files, but the ant is throwing an error that it cannot find an xml file within the jacocoant.jar. After extracting the files from the jar, the file is there, and has worked in other use cases of this build.xml.
Log from the command ant -v -debug
52336 $ ant -v -debug

While @Godin had the right answer for what was revealed by the stack trace. To resolve the issue is the following:
JaCoCo when dumping coverage information is an asynchronous task, and will not be available right away. It may take a few moments for the files to be completely written. Therefore we needed to automate an appropriate timeout before the environment that was creating these exec files would upload them into s3 (10 Seconds).
This was the case for AWS Ec2 instances.

According to stack trace at the end of your log - this has nothing to do with xml file within the jacocoant.jar , MergeTask fails:

And EOFException indicates reason of failure - file 10001.exec is corrupted, see https://github.com/jacoco/jacoco/pull/397
