OK. I have maven produce a classpath file for me so I know what classpath
it is using.
I created a shell script to execute a single junit test outside of maven.
Using org.junit.runner.JUnitCore I am executing
org.apache.jena.tdb2.assembler.TestTDBAssembler
I get:
.E.E.E.E.E.E.org.apache.jena.dboe.base.file.AlreadyLocked: Failed to get a
lock:

The tdb.lock file does not exists before or after the run so it does get
cleaned up.
At the bottom of the above exception the output goes on with:

... 61 more
errors 1 through 6 are the NoClassDefFoundErrors all missing
BPlusTreeFactory while error 7 is the existence of the lock file. I
suspect the first reporting of the error simply shows the last error and
then lists all the errors.
I have checked and the jar with BPlusTreeFactory
(jena-dboe-trans-data-3.10.0-SNAPSHOT.jar) is on the classpath and does
contain the BPlusTreeFactory.
So does the TDB2 system somehow build a new classpath? Does the test
system create a new classpath? Is there some way the original classpath
could have been modified before the test was called?
Any assistance is appreciated.
