error running maven tests on master

[duke-arioch]

Am I doing something wrong?

When running mvn clean install I get the below error (after successful 64-bit python setup.py install) but it doesnt say what the missing dependent libraries are. Not sure at all what to do here?

org.jpy.PyLibTest Time elapsed: 0.001 sec <<< ERROR!
java.lang.UnsatisfiedLinkError: C:\workspaces\jpy\build: Can't find dependent libraries
at java.lang.ClassLoader$NativeLibrary.load(Native Method)

at org.jpy.PyLibTest.setUpClass(PyLibTest.java:27)

this is after i changed the code that was occurring in my other issue about compiling with 1.8.

in pyobject:

public void setAttribute(String name, Object value) {
    assertPythonRuns();
    Class clazz;
    if (value != null) {
        clazz = value.getClass();
    } else {
        clazz = null;
    }
    PyLib.setAttributeValue(getPointer(), name, value, clazz);
}

also had to add this otherwise got the below exception:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>

                        <jpy.jpyLib>C:\app\python\Lib</jpy.jpyLib> 
                    </systemPropertyVariables>
                </configuration>
            </plugin>

python setup final output was:

jpy binary build is 'build\jpy.win-amd64-3.4.zip'

java.lang.UnsatisfiedLinkError means, Java VM can't find the the DLLs which were just built. I'll have a look into this on Monday. Does it only appear with your 1.8 change?

i backed out my changes and got exceptions in the test runs - what should
this be set to?

Caused by: java.lang.RuntimeException: missing configuration property
'jpy.jpyLib'
at org.jpy.PyLibConfig.getProperty(PyLibConfig.java:117)

I then set the property to C:\app\python\Lib and got the same error.

Thanks for the quick reply and looking into my problem!

There is also an option to call Maven directly from the Python setup script. Have you tried:

python.exe setup.py --maven build

Also, have a look into the setup.py code, line 368: here you can see how Maven is invoked using the current jpy configuration.
