Hi Marc,
Thanks for your suggestion! I tried the get executiondata and successfully run
the offline instrument -> deploy to GAE -> collection data. I got the .exec
file in the google cloud storage, but the:
Caused by: java.io.IOException: Invalid execution data file.
at
org.jacoco.core.data.ExecutionDataReader.read(ExecutionDataReader.java:89)
at org.jacoco.core.tools.ExecFileLoader.load(ExecFileLoader.java:59)
at org.jacoco.ant.ReportTask.loadExecutionData(ReportTask.java:514)
... 25 more
when I try to get the report from the exec file. This file is send through the
google's api and I try to write the byte[] in the output stream and save as a
.exec file. Not sure whether the invalid file is due to this byte[] to file
save process. We used to try to save the coboertura data file by write the
whole data object and it can parse after the donwload.
