Same type of output for each module but doesn't seem to analyze the file

... then it runs out of memory

In SQ 6.7, each module gets indexed separately, but with the
new SQ 8.9 it tries to analyze the whole project at once.
Also this is what I see in the output which is not in the old:


16:02:11 INFO: Base dir: ../trt/all/src < this is the root of the project>
16:02:11 INFO: ../trt/all/src/.scannerwork
16:02:11 INFO: Load project settings for component key: 'trt-all:develop'
16:02:11 INFO: Load project settings for component key: 'trt-all:develop' (done) | time=21ms
16:02:11 INFO: Auto-configuring with CI 'Jenkins'


So definitely adding ':<branch>' in the sonar.projectKey messes things up. I don't know what component means here.
