Not able to run sample code of OpenCV/Caffe JavaCpp Preset. Getting "java.lang.NoSuchMethodError: init"

Hi

My pom looks like:

        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>javacpp</artifactId>
            <version>1.1</version>
        </dependency>

    <dependency>
        <groupId>org.bytedeco</groupId>
        <artifactId>javacv</artifactId>
        <version>0.10</version>
    </dependency>

      <dependency>
        <groupId>org.bytedeco.javacpp-presets</groupId>
        <artifactId>caffe</artifactId>
        <version>master-1.1</version>
      </dependency>

     <dependency>
      <groupId>org.bytedeco.javacpp-presets</groupId>
      <artifactId>opencv</artifactId>
      <version>2.4.11-0.11</version>
     </dependency>

Command I am running:

mvn package exec:java -Dplatform.dependencies

Error I get:

Build machine : MacBook OS X El Capitan 10.11.3
Java version 1.8

Can someone help please ? I am going to try the manual installation steps as given in github readme. But if there is any glaring mistake in my setup above, please let me know. Thanks.

This problem got solved. Seemingly there were two versions of javaCpp in my .m2 maven directory. And the unintended one was getting picked. Clearing all presets and doing clean install did the tricks. Thanks.

There's also that JavaCV 0.10 isn't compatible with JavaCPP 1.1...

Thanks. You are right. I think that was the problem. I went back in the history of my pom.xml and realized that version of OpenCV and Caffe presets I had used belonged to different JavaCpp versions.
