问题
I'm trying to configure the SonarQube 4.5.4 on my server. For that SonarQube version, it needs jdk 1.7, in case of building my Android system firmware, only jdk 1.6 can be set as the default jdk.
Now jdk 1.7 is still on my Computer, not the defalut one. So in order to make SonarQube run, the jdk 1.7's absolute path is specified in /conf/wrapper.conf under the following line:
wrapper.java.command=/usr/lib/jvm/java-7-oracle/jre/bin/java
After this, the jdk 1.7 can be seen from Sonar's setting:
Ok, the sonar-runner is ready to analysis a demo code. Unfortunately, an error was throw:

Since the jdk 1.7 is already set for SonarQube 4.5.4, why does it throw this error? Should I still need to specify jdk 1.7 for Sonar-runner, but I didn't find the place to configure it.
回答1:
Specify a java for Sonar-runner in a hack way:
- Edit the file
<sonar_runner_directory>/bin/sonar-runner - Find the line
JAVA_CMD="'which java'" - Change the command with your target java's absolute path, like mine:
JAVA_CMD=/usr/lib/jvm/java-7-oracle/jre/binjava.
