Jenkins中配置gradle项目的坑

Posted 2022-12-12 Q博士

今天在jenkins配置gradle项目时遇到一个奇特的问题记录如下：

问题

在jenkins配置gradle项目如下所示：

我的目的是想执行gradle clean build run任务，但是构建的时候出现如下的错误：

[Gradle] - Launching build.
[workspace] $ /Users/wuxian/.jenkins/jobs/TestReportSender_test/workspace/gradlew clean build run

ok，既然这个是默认调用gradlew的，我们就换一个方式，然后我选择了另一个选项，配置如下：

ok，我们构建项目，发现成功了。但是我们从输出中可以看出来，明显是调用了下面的配置，这就很明显配置串了。

[Gradle] - Launching build.
[workspace] $ gradle clean build run
:clean
:compileJava
:processResources
:classes
:jar
:startScripts
:distTar
:distZip
:assemble
:compileTestJava
:processTestResources
:testClasses
:test
:check
:build
:run

BUILD SUCCESSFUL

后来搜索了一下这个问题,发现这个是bug。

总结

为了在jenkins中使用gradle,需要选择Invoke gradle script选项，然后还必须在Use gradle wrapper选项中配置你要跑的任务(但是你千万不能选择该选项，否则jenkins会默认调用gradlew程序执行任务，但是一般你配置gradle后，没有该程序，就会报错)，才能成功的利用gradle程序构建你的程序。fuck。

其他问题

上面的问题在我的master机器上使用是可以的，但是移到slave机器上使用的时候就出现问题了。又报了一个错误：

[ios_CI_step5_TestReportSender] $ gradle
FATAL: command execution failed
java.io.IOException: Cannot run program "gradle" (in directory "/Users/a58/jenkins/workspace/iOS_CI_step5_TestReportSender"): error=2, No such file or directory

    at hudson.remoting.UserRequest.perform(UserRequest.java:49)
    at hudson.remoting.Request$2.run(Request.java:324)

所以我放弃了，我直接使用shell命令吧…

source ~/.bash_profile
gradle clean run

然后又好使了：

+ gradle clean run
:clean
:compileJava
:processResources
:classes
:run
