Java/jpl cmake test errors

swi · April 16, 2020, 5:09am

I am getting the following errors when testing jpl:

Both suggest a mixup of versions, combining a wrong version of libswipl.so, jpl.so and/or jpl.jar. Maybe some environment variable leading to an old version, an old file copied to place where it is first found by the dynamic linker or Java, etc.

Of course it can be something else. So far these tests passed for the most recent build on all platforms.

Thanks, the jpl submodule had not updated properly. Now I am getting a new error:

It happens because JUnit 4.11 and above require hamcrest-core.jar in the class path, as shown in this stackoverflow question. I do have it:

$ ls -al /usr/share/java/hamcrest-core.jar
lrwxrwxrwx 21 root  5 Jun  2018  /usr/share/java/hamcrest-core.jar -> hamcrest/core-1.3.jar

but it is not included in the classpath (from the error above):

ssardina · April 17, 2020, 11:02am

Thanks for pointing this out; I recently updated JPL and migrated JUnit from v3 to v4, and also clean that up a lot (still a much bigger clean-up and restructuring is in a branch)

You are right that JUnit4 seems to require hamcrest-core.jar, and I do have it in my system as you but the test passes well (or any individual call via Java) without that being in the classpath…

Need to investigate, I have re-opened issue #40 related to this transition:

ssardina · April 17, 2020, 12:22pm

Hi @swi,

JUnit4 needs hamcrest-core.jar and I have them both in /usr/share/java.

What I find strange in your trace is that it is looking for /usr/share/java/junit.jar which is not correct as that is v3. It should look for /usr/share/java/junit4.jar and then it will pick up the dependency automatically.

See the command that cmake runs:

62: Test command: /usr/bin/env "SWI_HOME_DIR=../../home" "SWIPL_BOOT_FILE=../../home/boot.prc" "TEST_JPL=../../../packages/jpl/test_jpl.pl" "/usr/lib/jvm/java-8-oracle/bin/java" "-Djava.library.path=." "-classpath" "/usr/share/java/junit4.jar:src/java/jpl.jar:src/java/jpltest.jar" "org.jpl7.test.junit.Tests"

I did modify the framework to look for junit4.jar and not junit.jar, not sure why your system is picking that one up instead:

Since you seem to have a development version of SWI-JPL, maybe you want to try the latest junit4 branch which has the tests in better shape? I am curious if it also picks up junit.jar

swi · April 17, 2020, 4:43pm

Hi @ssardina,

Thank you for your reply, I am using archlinux and the junit package comes with these files:

/usr/share/java/junit-4.12.jar
/usr/share/java/junit.jar

and

$ ls -al /usr/share/java/junit.jar
lrwxrwxrwx 14 root  4 Jun  2018  /usr/share/java/junit.jar -> junit-4.12.jar

As you can see junit.jar is a symlink to junit-4.12.jar. This is done automatically by the archlinux package management system.

Perhaps you could modify the cmake script to find any file with the regex patern junit.?4.*\.jar
This would match both junit4.jar and junit-4.12.jar, I’ll be happy to test that.

ssardina · April 19, 2020, 12:05pm

Hi @swi

ahh I see, great stuff you gave me. OK I have followed your advice and now search for those patters for junit. Unfortunately GLOB for CMAKE does not find files by regexp so it was a bit more explicit but should work.

Would you be able to test branch enhacement/junit4 to see if it works? It also contains all the tests much better organized in test suites (and additional tests that were standalone tests), so don’t be alarmed if you see a much verbose output when you run the test!

Let me know how it goes. And if it works I will make a PR to go into master.

Thanks!

Thanks @swi for trying quick, that helps a lot!

Sorry, somehow a wrong text (RationalTest.class) from another branch got into the last commit wrongly!

I have fixed that, can you pull again and re-try. Thanks!

As you can see it does recognize the junit-4.12.jar - so your fix for that is working; but it does not add the hamcrest-core.jar file to the class path.

My hamcrest-core.jar is in /usr/share/java (it is a symlink):

$ ls  /usr/share/java/hamcrest-core.jar
/usr/share/java/hamcrest-core.jar

ssardina · April 20, 2020, 7:25am

OK we are getting there. Your JAR was found. Thanks for testing it, very helpful as I can only test in my configuration!

I thought the dependency would be found automatically because JUNIT jar includes it in its MANIFEST.MF

Implementation-Title: JUnit
Implementation-URL: http://junit.org
Implementation-Vendor: JUnit
Implementation-Vendor-Id: junit
Implementation-Version: 4.12
Import-Package: org.hamcrest;version="1.3",org.hamcrest.core;version="1.
  3"

Wonder if your JUNIT JAR has that part.

In any case, I have changed the script to explicitly add it to the CLASSPATH. Can you pull and check?

swi · April 20, 2020, 8:30am

Thanks! It found the hamcrest jar now. Now I get this error:

It seems it can’t find test_jpl.pl. The file does not exist in the cmake build directory, but it is found in the original src directory:

$ find packages/jpl -iname 'test_jpl.pl'
$ find ../packages/jpl -iname 'test_jpl.pl'
../packages/jpl/src/java/org/jpl7/test/test_jpl.pl

ssardina · April 20, 2020, 8:55am

Hi. Thanks for running it quickly, it helps me a lot.

Yes test_jpl.pl is in the original source dir. I have fixed and simplified the dir and TEST_FILE was not needed. Strange why it didn’t give me error here, but the path is anyways way too complicated as it is.

can you pull and try? Seems we are making together prioress step-by-step! THANKS!

Note that the test_lib CMake function from SWI-Prolog does not use the TEST_DIR parameter, it uses the following to figure out the prolog source file for testing:

set(test_source "${CMAKE_CURRENT_SOURCE_DIR}/${test_source_basename}")

So it expects the test_jpl.pl file as packages/jpl/test_jpl.pl

mmmm thanks for staying with me.

So, seems the prolog_in_java test now works on your side then?

But now I see the problem now is java_in_prolog, yes good pointer let me check and fix that as well.

ssardina · April 20, 2020, 9:39pm

So it was not a good idea to move test_jpl.pl inside the source tree, as it does not follow the “standard” for test_xxx.pl on all the other packages.

I reverted that back and adapted all tests. Hopefully this will work on both tests for you, let me know! Thanks!

OK I know that! Yes this is because I am developing both on CMAKE and IntelliJ, a bit of a mix.

Now I have sorted all out I think and do not use TEST_DIR anymore.

Can you check one more? Sorry! I bet this is the last one!

Happy to help! Working great now, with no exceptions!
