I am using the embedded H2 database.
Sonar version is 6.5 and installed on Windows 7.
The file upload completes successfully when the compressed content is < 50 KB in size (I am guessing, based on how it has worked out for me).
This always fails for me:
[INFO] Analysis report generated in 1022ms, dir size=384 KB
[INFO] Analysis reports compressed in 3019ms, zip size=190 KB
Anything beyond that fails with the above exception.
Are you aware of any setting that limits the size of the file being uploaded to SQ server?
Any help will be high appreciated.
