我的环境如下：
http://localhost:9000/sonar/api/server/version :: 5.2
java,sonar-java-plugin-3.7.jar|07dba2b9cad37584d82522414b2dccd0
scmgit,sonar-scm-git-plugin-1.0.jar|e1d9d8e1d3524f9f0f69017e6dbead02
scmsvn,sonar-scm-svn-plugin-1.2.jar|188d526ad86ec7f2dc7de694bf5f1851
printenv | grep MAVEN<BR>
MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=512m
我启动命令：
mvn sonar:sonar -Dsonar.verbose=true
它失败了，如下所述。
如果我在 SonarQube Global Source File Exclusions 中插入文件MyFileName.java（参考回溯），则该过程继续进行，直到下一个文件（可能是下一个需要跟踪的文件，因为它受到某些问题的影响）并且它失败再次出现相同的症状。
文件中没有具体的踪迹sonar.log。
与以下结果相同：
mvn org.codehaus.mojo:sonar-maven-plugin:2.6:sonar -Dsonar.verbose=true
我要分析的主要项目非常广泛，失败的“模块”是第 103 个；这只是说在前面的阶段已经处理了几个模块，没有任何声纳故障。
关于如何调查此问题的任何建议？
