有没有办法启用Maven调试模式(-X)以获得仅与maven插件的具体执行相关的调试信息？
所有maven步骤的调试信息都太大,无法保存和分析.
我使用以下代码通过ExoPlayer播放音乐流:
exoPlayer = ExoPlayer.Factory.newInstance(numRenderers, minBufSize, maxBufSize);
String url = Helper.getPr().getString("url", "http://mp3.nashe.ru:80/ultra-128.mp3");
Uri uri = Uri.parse(url);
Log.i(TAG, "Going to open " + url);
Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);
DataSource dataSource = new DefaultUriDataSource(getApplicationContext(), USER_AGENT);
ExtractorSampleSource sampleSource = new ExtractorSampleSource(uri, dataSource, allocator, BUFFER_SEGMENT_COUNT * BUFFER_SEGMENT_SIZE);
audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource);
exoPlayer.addListener(this);
exoPlayer.sendMessage(audioRenderer, MediaCodecAudioTrackRenderer.MSG_SET_VOLUME, volume);
exoPlayer.prepare(audioRenderer);
exoPlayer.setPlayWhenReady(true);
我找不到有关如何获取艺术家和当前歌曲名称等元数据的任何信息.是否可以获取元数据,如果是,如何？
非常感谢.
我已经在openshift上设置了Jenkins,制作了一个hello world项目并尝试在openshift中由Jenkins打包.但我得到了下一个错误:

我认为它与OPENSHIFT_INTERNAL_IP有关,但是如何解决这个问题呢？
我正在尝试为 maven 项目模块之一禁用 maven-pmd-plugin 的执行，但找不到可行的解决方案。
现在我在模块中有下一个：
<properties>
<cpd.skip>true</cpd.skip>
<pmd.skip>true</pmd.skip>
<maven.pmd.enable>false</maven.pmd.enable>
<maven.pmd.cpd.enable>false</maven.pmd.cpd.enable>
</properties>
并在调试输出中包含下一个：
