在代理上在Groovy脚本中查找文件中的行数

Question

我编写了一个groovy脚本，用于使用运行静态代码分析，并希望将所有发现的问题存储在.txt文件中。然后需要在该.txt文件中找到行数，如果它大于1，则需要向相关人员发送电子邮件。我为这个groovy脚本编写的代码如下：

def call(Map coverityParams){
  echo "${coverityParams.defectsFileName}"
  bat """
        cov-analyze --dir ${coverityParams.tempDir} --all --security ${coverityParams.securitySwitch}
        cov-commit-defects --dir ${coverityParams.tempDir} --stream ${coverityParams.stream} --host 172.16.15.34 --auth-key-file ${coverityParams.authKeyFile}
        cov-manage-im --mode defects --show --host 172.16.15.34 --stream ${coverityParams.stream} --user=${coverityParams.userName} --password=${coverityParams.password} --status New > ${coverityParams.defectsFileName}
     """
     int DEFECTS_COUNT = bat(
                script: find /v \"\" /c < \"${coverityParams.defectsFileName}\",
                returnStdout: true
            ).trim().toInteger()
            DEFECTS_COUNT = DEFECTS_COUNT - 1
            echo "Defects Count is ${DEFECTS_COUNT}"
            if(DEFECTS_COUNT > 0){
                echo "Defects Count is ${DEFECTS_COUNT}"
                mail (body: 'You have ' + DEFECTS_COUNT + ' new coverity defects introduced. Please go to ' + "${coverityParams.viewName}" + ' view on http://172.16.15.34:8080/ ', subject: DEFECTS_COUNT + ' new coverity issues detected.', to: "${coverityParams.mailTo}")
            }
}

运行时，Jenkins将抛出以下错误

据我所知，这与将字符串转换为数字有关。我认为问题在于我的脚本正在返回1"而不是1，这就是为什么toInteger()无法将它转换为数字。但我无法找到解决这一问题的办法。

Answer 1

因此，下面的代码片段可以用于您的案例

script {
    // some block
    def DEFECTS_COUNT_STR = bat(
                script: '''find /v "" /c < "somefile.txt"''',
                returnStdout: true
            ).trim().split("\n")
    int DEFECTS_COUNT = DEFECTS_COUNT_STR[1].toInteger()
    echo "$DEFECTS_COUNT"
}

现在是什么问题，\m。在您的例子中的问题是，您正在得到一个字符串，如下所示：

"C:\JenkinsWS\workspace\gwp-master>find /v "" /c  0<"GWDefects.txt" 
1"

这是两条线。1蝙蝠在哪里和什么地方被执行，第二次你的结果。你需要结果。所以最好的方法是拆分它，然后丢弃第一个输出，使用第二个输出，然后转换为整数。

编辑:我应该更新你的代码。下面是您的代码的样子

def call(Map coverityParams){
  echo "${coverityParams.defectsFileName}"
  bat """
        cov-analyze --dir ${coverityParams.tempDir} --all --security ${coverityParams.securitySwitch}
        cov-commit-defects --dir ${coverityParams.tempDir} --stream ${coverityParams.stream} --host 172.16.15.34 --auth-key-file ${coverityParams.authKeyFile}
        cov-manage-im --mode defects --show --host 172.16.15.34 --stream ${coverityParams.stream} --user=${coverityParams.userName} --password=${coverityParams.password} --status New > ${coverityParams.defectsFileName}
     """
     def DEFECTS_COUNT_STR = bat(
                script: find /v \"\" /c < \"${coverityParams.defectsFileName}\",
                returnStdout: true
            ).trim().split("\n")
     int DEFECTS_COUNT = DEFECTS_COUNT_STR[1].toInteger()
            DEFECTS_COUNT = DEFECTS_COUNT - 1
            echo "Defects Count is ${DEFECTS_COUNT}"
            if(DEFECTS_COUNT > 0){
                echo "Defects Count is ${DEFECTS_COUNT}"
                mail (body: 'You have ' + DEFECTS_COUNT + ' new coverity defects introduced. Please go to ' + "${coverityParams.viewName}" + ' view on http://172.16.15.34:8080/ ', subject: DEFECTS_COUNT + ' new coverity issues detected.', to: "${coverityParams.mailTo}")
            }
}
