Javacv: cannot use self-built javacv

[The-Crocop]

Hi Samuel I have builld all the javacv ,javacpp-presets and javacpp libraries myself. Im using Ubuntu and gradle.

I have those entries in my build.gradle:

repositories{
    mavenCentral()
    mavenLocal()
}
dependencies {
    compile 'org.bytedeco:javacv:1.2-SNAPSHOT'
    compile("org.bytedeco.javacpp-presets:opencv:3.1.0-1.2-SNAPSHOT:linux-x86_64")
    compile("org.bytedeco.javacpp-presets:ffmpeg:3.0.1-1.2-SNAPSHOT:linux-x86_64")
}

However the javacv dependency causes this error:

 Could not resolve all dependencies for configuration ':compile'.
 Could not find javacpp-presets-${os.name}-${os.arch}.jar (org.bytedeco:javacpp-presets:1.2-SNAPSHOT).
   Searched in the following locations:
     file:/home/user/.m2/repository/org/bytedeco/javacpp-presets/1.2-SNAPSHOT/javacpp-presets-1.2-SNAPSHOT-${os.name}-${os.arch}.jar

Any idea what might cause this?

I have build javacpp-presets with these commands:

bash cppbuild.sh -platform linux-x86_64 install
mvn clean install -Djavacpp.platform=linux-x86_64 -Djavacpp.platform.dependency=false

I have build javacv like this:

mvn clean install -Pffmpeg.

It looks like Gradle doesn't resolve the os.name and os.arch properties like Maven does. AFAIK, to get Gradle working perfectly, we would need to create a small special project for that. @lloydmeta has created sbt-javacv and sbt-javacpp to resolve these issues with sbt. Would you be interested in making the same thing for Gradle?

[The-Crocop]

Sure. Id love to do that. Just give me some time.

Great! Keep me updated on your progress

I guess we shouldn't break things that used to work, even if it's caused by a bug in Gradle, so marking this as a bug. The workaround is to include this in the build.gradle file:

configurations {
    all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
}

The JavaCPP Presets and JavaCV 1.3 now rely on "platform artifacts", so we won't be having issues like this anymore with either Gradle or sbt! Thanks for reporting
