sonar-scanner报错 ERROR: SonarQube server [http://localhost:9000] can not be reached和Not authorized. A

1、jenkins工作目录的项目下添加sonar-project.properties文件，具体内容如下：

 

# must be unique in a given SonarQube instance
sonar.projectKey=seleniumdemo
# this is the name displayed in the SonarQube UI
sonar.projectName=seleniumdemo
sonar.projectVersion=1.0
# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# Since SonarQube 4.2, this property is optional if sonar.modules is set.
# If not set, SonarQube starts looking for source code from the directory containing
# the sonar-project.properties file.
sonar.sources=src
# Encoding of the source code. Default is default system encoding
#sonar.sourceEncoding=UTF-8
#path to your project build output path
sonar.java.binaries=target/classes

2、进入项目的跟目录，执行sonar-scanner命令，报如下错：

INFO: User cache: /Users/yp-tc-m-2935/.sonar/cache

ERROR:

解决方法：

sonarqube没有开启，启动sonarqube服务，不报此问题。

 

 

3、报错：

经过几个小时的排查，他妈的是 sonar scanner的sonar-scanner.properties配置文件的某个key写成大写了。。
