Question

我第一次在this tutorial之后测试vlcj，但是当我运行它时，我得到了这个错误输出：

cd C:\Users\abolfazl\Documents\NetBeansProjects\testplayer; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_05" cmd /c "\"\"C:\\Program Files\\NetBeans 8.0\\java\\maven\\bin\\mvn.bat\" -Dexec.args=\"-classpath %classpath com.mycompany.testplayer.InformationLib\" -Dexec.executable=\"C:\\Program Files\\Java\\jdk1.8.0_05\\bin\\java.exe\" -DnetbeansProjectMappings= -Dmaven.ext.class.path=\"C:\\Program Files\\NetBeans 8.0\\java\\maven-nblib\\netbeans-eventspy.jar\" org.codehaus.mojo:exec-maven-plugin:1.2.1:exec\""

我的InformationLib.java是：

import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;
import uk.co.caprica.vlcj.binding.LibVlc;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;
import uk.co.caprica.vlcj.runtime.x.LibXUtil;

public class InformationLib {

    public static void main(String[] args) throws Exception {
         System.out.println("aaaaaa");
        NativeLibrary.addSearchPath(
                RuntimeUtil.getLibVlcLibraryName(), "d:/vlc-2.2.1");
        Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
        LibXUtil.initialise();       

        System.out.println("  version: {}" + LibVlc.INSTANCE.libvlc_get_version());
        System.out.println(" compiler: {}" + LibVlc.INSTANCE.libvlc_get_compiler());
        System.out.println("changeset: {}" + LibVlc.INSTANCE.libvlc_get_changeset());
    }
}

错误表明您的计算机无法解析主机名repo.maven.apache.org，这是导致失败的原因。主机名在这里解析得很好，找到了maven存储库。所以我认为这是您本地DNS的一些问题。

运行时vlcj.jar的问题
