SonarScanner运行报错：无法连接数据库?报错

黑框是 sonar-scanner报的错？有提示加-e参数查看详细错误堆栈了，有试过吗？详细错误堆栈贴出来看看？下面白框应该是sonarweb的日志吧，最好提问描述清晰一下上下文哦，比如执行了哪个命令报，就丢个链接这样很难有人有时间猜测一下再研究一下再跟你交流的。

目前学习Sonar工具来分析源码。

以下是操作步骤

1.配置数据库，创建一个sonar数据库。

2.启动Sonar服务，通过sonarqube安装目录下的sonar.properties文件初始化数据库（数据库初始化成功）

3.利用SonarScanner工具执行源码分析。需要配置环境变量name=SONAR_RUNNER_HOME。value=D:\sonar\sonar-scanner-2.5，并且在需要分析的项目根目录，创建建sonar-project.properties文件，以上工作全部完成。

4.启动sonarqube服务，并启动cmd，在cmd进入项目所在的根目录，输入命令：sonar-runner

正常是能执行代码分析的，但是此处加载插件时失败。（可以排除各个软件版本的问题）

我现在是找到问题所在了，但是为什么造成这样不清楚

请教加载失败的原因。我把在同事电脑正常加载.sonar是文件夹拷贝到根目录下，依旧是报相同的错误，还是得需要它自己正常加载。

sonar-ruuner执行分析之前是要从sonarweb下载插件，你这种情况应该是下载失败了，建议取你同事的环境拷贝 Sonar／sonarqube-5.3/extensions/plugins下的插件。然后重启sonarweb。再试试
