Test Failures during mvn install?

[Booley]

I'm trying to install javacpp on OSX with mvn install:

git clone https://github.com/bytedeco/javacpp
cd javacpp
mvn clean
mvn install

But the install fails with these errors:

How can I fix these test failures?

[saudet]

That's a new one. I wonder what causes that. You can skip the tests for now by calling mvn clean install -Dmaven.skip.test

[saudet]

BTW, what version of Maven is this?

[Booley]

This is maven 3.3. Skipping the tests worked, thanks!

[Booley]

Ahhhh actually, that command didn't work, I actually ran mvn clean install -DskipTests earlier and that worked, but I just ran with the -Dmaven.skip.test option instead and that still results in the failed tests; I thought they were equivalent commands but apparently not.

I opened another issue at bytedeco/javacpp-presets#154 about building the caffe presets, and I'm wondering if it's possible these are related?

After running mvn clean install -DskipTests in the javacpp directory successfully, I used that jar file in an Eclipse project and tried running:

import org.bytedeco.javacpp.*;

public class Test {
    public static void main(String[] args) {
        BoolPointer p = new BoolPointer();
        p.put(true);
    }
}

just to see if the javacpp.jar built correctly (and not concerning the presets at all), but it outputs this error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.bytedeco.javacpp.BoolPointer.put(IZ)Lorg/bytedeco/javacpp/BoolPointer;
    at org.bytedeco.javacpp.BoolPointer.put(Native Method)
    at org.bytedeco.javacpp.BoolPointer.put(BoolPointer.java:74)
    at Test.main(Test.java:8)

I assume the javacpp.jar file was not meant to ever be used by itself, but I thought a simple test like this ought to work. Does this mean something is wrong with the jar, or was I not meant to access it like this in the first place? Is it possible these failed tests are what prevent me from using the presets correctly?

[saudet]

Sorry, I meant mvn clean install -Dmaven.test.skip. Yes, JavaCPP wasn't meant to run standalone, but it could be modified to... Anyway, check the test subdirectory for a way around that.

[saudet]

Yes, it looks like your installation of Maven is picking up an old version of JavaCPP somewhere, and that's probably why the tests fail.

[Booley]

Thanks for the quick reply! That command works, but unfortunately I keep getting UnsatisfiedLinkErrors when using the jars (specifically, opencv). I tried deleting my .m2 directory and reinstalling maven, but no difference. I'm just wondering, are there any prerequisites for using javacpp on OSX that maybe I'm forgetting about (e.g. specific OSX version or maybe Xcode dependencies)?

Right now I'm trying to narrow down the problem by seeing if there's something wrong with javacpp.jar before I start combining it with any of the presets, since they all build correctly but are apparently not usable. Is there a super short test program you recommend I try to verify if my built version of javacpp.jar works, such as by calling a specific function? I can reference all class constants normally, but not the functions. Otherwise, I'll keep investigating my maven installation.

[saudet]

Let's see, did you check this list? https://github.com/bytedeco/javacpp-presets/wiki/Build-Environments#mac-os-x-x86_64

[Booley]

As it turns out I didn't have quite a few things there installed, so that was extremely helpful! Unfortunately, that didn't affect the build: I can build javacpp.jar only by skipping the tests, and I can build a preset successfully, but when I use them I get UnsatisfiedLinkedError.

I noticed that when I run sh cppbuild.sh install opencv the output here:

Under OpenCV Modules->Disabled, it says java. Also, under Java it says Java wrappers: NO. Is this problematic, or is it that the presets are built during some separate stage, so the wrappers should not be built during cppbuild.sh?

[saudet]

It's not the same wrappers no. JavaCPP is closer to the C++ API.

[Booley]

Ahhh hot diggity dawg it works!!!!!!!! You were right, it was a combination of not having the right packages installed and having an old javacpp.jar (built before installing those packages) on my classpath. I cleaned out everything and rebuilt, and it works perfectly now--no failed tests and no UnsatisfiedLinkError anymore. Sorry for causing you trouble, but thank you so much for your help! :)

[saudet]

Great :) No problem

[naderigolshan]

Thanks to Booley for mvn clean install -DskipTests.
