SonarQube在插件开发期间无法重启

Question

我正在为SonarQube 4.5.4/5.0.1开发一个插件.我想使用sonar-dev插件上传一个JAR文件并快速重启SQ服务器.插件使用REST API(/api/system/restart),它通过设置sonar.dev=true属性启用.

这是配置:

<plugin>
    <groupId>org.codehaus.sonar</groupId>
    <artifactId>sonar-dev-maven-plugin</artifactId>
    <version>1.8</version>
    <configuration>
        <sonarHome>F:\sonarqube-5.1\sonarqube-5.1</sonarHome>
    </configuration>
</plugin>

问题是每次重启尝试后服务器崩溃,我必须手动重启,这令人沮丧,并降低了我的工作效率.这是"重启"后每个后续请求返回的堆栈跟踪.

这是 从第71行开始的日志中发生的事情.

根据@Simon Brandhof,它可能与锁定文件的类加载器相关联.任何线索或变通方法都非常感激.

Java插件似乎锁定了它的类加载器.通过删除卸载它extensions/plugins/sonar-java-plugin-3.0.jar应该可以解决问题.
