Devops - build fails on tests due to disk limits

[extua]

Following on from issue #160, I am now building with gradle 5.6.4, but the build fails the following tests:

org.webcurator.core.visualization.networkmap.NetworkMapUtilTest > testGetNextTitle FAILED

FAILURE: Build failed with an exception.

The specific exception in all these cases is

com.sleepycat.je.DiskLimitException: (JE 18.3.12) Disk usage is not within je.maxDisk or je.freeDisk limits and write operations are prohibited: maxDiskLimit=0 freeDiskLimit=5,368,709,120 adjustedMaxDiskLimit=0 maxDiskOverage=0 freeDiskShortage=1,511,313,408 diskFreeSpace=3,857,395,712 availableLogSize=-1,511,313,408 totalLogSize=1,427 activeLogSize=1,427 reservedLogSize=0 protectedLogSize=0 protectedLogSizeMap={}

I have about 80GB of free space on my laptop, so pretty sure that's not the issue. I can see this has come up in Heratrix before, with a solution to increase the FREE_DISK variable.

I was able to get past this by adding

environmentConfig.setConfigParam(EnvironmentConfig.FREE_DISK, "0");

to the BDBRepoHolder.java file as suggested in this comment.

I don't know a better way to raise the disk limit, anyway this works for now.

Setting the disk limit to zero just removes the free space limit, in the meantime I've set my limit to 1073741824 (10GB), which also passes the test.
