Re: Can't build tdb2

Sun, 14 Oct 2018 07:48:01 -0700 

Did yuo run the build from the top, from jena-db or just jena-tdb2?

In a little more detail,  I ran "mvn clean install -Pdev" and the build

In jena-tdb2 directory the I ran "mvn dependency:build-classpath
-Dmdep.outputFile=cp.txt"


Does cp.txt include the test classes mentioned?




which generated a file with the classpath for the build.  I created a
script using that classpath as well as the target/classes and
target/test-classes directory to execute org.junit.runner.JUnitCore
org.apache.jena.tdb2.assembler.TestTDBAssembler

My goal was to remove any maven issues and try to get to the simplest
possible execution.  But I got the same errors as with the mvn build.  I
can not figure out how the classpath gets modified so that the
jena-dboe-trans-data-3.10.0-SNAPSHOT.jar is not found.

It makes no difference if I run the test with Eclipse running or not.
It makes no difference if I run the tests with Maven or not.

How are you running tests and your IDE?
I use the mavenr nature of projects, not the old command line "generate
.classpath" etc.

For a new version, in Eclipse you must do Alt-F5 (Maven update) for
everything; it is also good to do maven and also it is cleaner to do a
maven build locally beforehand.  This puls down the non-java POMS which
get out of step is the parent is not open in Eclipse.

No producing .classpaths etc m2e does it automatically.

I don't see how it could.

"mvn clean install -Pdev" works for me locally.

I created a shell script to execute a single junit test outside of maven.

The tdb.lock file does not exists before or after the run so it does get

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.
Claude

I have found that sometimes, Eclipse notices changes due "mvn clean"
then Eclipse and mvn compete to build things.  Generally, leaving the
Eclipse UI alone is OK (not perfect).
