如何从 build.gradle 中提取版本到 Jenkins 管道

Question

我正在尝试从 build.gradle 中提取我的应用程序版本，但我并没有如我所愿。

在我的 build.gradle 上，我有几个属性和我想要的一个：

版本 = '1.4.1-快照'

所以，在我的 Jenkinsfile 上，我做了：

def version_value = sh(returnStdout: true, script: "cat build.gradle | grep -o 'version = [^,]*'").trim()
sh "echo Project in version value: $version_value"
def version = version_value.substring(0, version_value.indexOf('='))
sh "echo final version: $version"

我收到以下错误：

+ cat build.gradle
+ grep -o version = [^,]*
[Pipeline] sh
[QR_CODE_GATEWAY] Running shell script
+ echo Building project in version value: version = 1.4.1-SNAPSHOT
Project in version value: version = 1.4.1-SNAPSHOT
+ version = 
/var/jenkins_home/workspace/PROJECT@tmp/durable-bbc0290d/script.sh: 3: /var/jenkins_home/workspace/PROJECT@tmp/durable-bbc0290d/script.sh: version: not found
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: script returned exit code 127
Finished: FAILURE

我很感激你的帮助。谢谢

您应该尝试使用split从“=”符号将字符串切割成 2 个数组。然后取第二个数组[1]：

def version_value = sh(returnStdout: true, script: "cat build.gradle | grep -o 'version = [^,]*'").trim()
sh "echo Project in version value: $version_value"
def version = version_value.split(/=/)[1]
sh "echo final version: $version"
