【原】Gradle调用shell脚本和python脚本并传参

最近由于项目自动化构建的需要，研究了下gradle调用脚本并传参的用法，在此作个总结。

Pre

build.gradle中定义了$jenkinsJobName $jenkinsBuild两个Jenkins变量，意图将gradle中的这两个值传到shell/python脚本中去用

def jenkinsBuild = System.getenv("BUILD_NUMBER") ?: "0"
println "jenkinsBuild is set to $jenkinsBuild" def jenkinsJobName = System.getenv("JOB_NAME") ?: "defaultJobName" println "jenkinsJobName is set to $jenkinsJobName"

Gradle调用shell脚本带参数

gradle task

task upload(type: Exec) {
    executable 'sh'
    args "-c","../shelldemo.sh $jenkinsJobName $jenkinsBuild"
}

shelldemo.sh脚本中

#!/usr/bin/env bash

#从build.gradle中传入的两个参数
jenkinsJobName=$1
jenkinsBuild=$2
echo "jenkinsJobName=$jenkinsJobName"
echo "jenkinsBuild=$jenkinsBuild"
...

Gradle调用python脚本带参数

gradle task

task uploadpython(type: Exec) {
    workingDir './'
    commandLine "python","pythondemo.py", "$jenkinsJobName", "$jenkinsBuild"
}

pythondemo.py脚本

#encoding:utf8
import sys

jenkinsJobName=sys.argv[1]
jenkinsBuild=sys.argv[2]
print jenkinsJobName
print jenkinsBuild
...

Gradle Exec官方文档的说明

注意双引号

Groovy中只为双引号的字符进行插值，所以如果写了单引号，是不work的。

Groovy only performs String interpolation for double-quoted Strings. (That's one of the reasons why I use double quotes by default.) Try:

...
args "-c", "source dosomething.sh $arg"
