+## Troubleshooting
+
+The integration tests are not completely independent of the environment.
+
+You may run into one or more of the following errors when you attempt to execute the command
+```
+mvn clean verify -P java-integration-tests 2>&1 | tee log.txt
+```
+1. `[ERROR] No permision to create directory /scratch/...`  
+there are a couple ways to resolve this issue:
+* create a world writable directory named /scratch
+* create some other world writable directory and then define the environment variables RESULT_ROOT and PV_ROOT to point to that directory. If you want, you can create two directories to keep things separated.
