All instructions are here: https://github.com/bytedeco/javacpp-presets/#build-instructions
All the source that you need is from GitHub. Be sure to run mvn install for both the latest source of the javacpp and javacpp-presets modules.

Can we have default build to have these class but avoid everyone to rebuild? thanks.

Of course, but someone needs to make those builds :)

I tried to understand more detail about the issue and tried to rebuild, I met some issues and have some questions,

  1. By default, if we only need build javacv 1.0 sample, we only need to specified these in the pom file and it will auto pop the dependencies jar like javacv.jar, javacpp.jar and opencv.jar.


    org.bytedeco
    javacv
    1.0

  2. The issues with above solution is the auto pop javacv.jar,javacpp.jar and opencv.jar are built with specified system so we need to rebuild all these jar manually, right?

  3. For the build sequence, we need to first build javacpp.jar, then build javacpp-presets and make javacpp-presets uses built javacpp.jar but not depended on this in the pom file, right?

    org.bytedeco javacpp ${project.parent.version}

Then we build javacv to make it depend on the built javacpp.jar and opencv.jar.
Last we make sample depended on the build three jar file, is this correct?

  1. I tried to build javacpp with maven, I met an issue, here is the log, what I need to do? In the meanwhile, I am doing more try now.

@chinadragon0515 You're understanding is correct. JavaCPP is just not finding the default compiler for your platform, which is MSVC on Windows. Please install MSVC.
