Jenkins/Maven 构建因“无法在反应器中找到所选项目”错误而垂死

Question

我在 Cloudbees 构建服务上使用 Jenkins 并创建了一个多模块 Maven 项目。最近，我们从父 pom 中删除了一个项目，但是，当我们使用以下选项在 Jenkins 中运行构建时……

clean install -e -P qa -P cloudbees -DskipITs

工件会自动存储到附加到我们帐户的 Cloudbees 快照存储库中。然而，构建最终失败并出现以下“无法在反应器中找到所选项目：org.mainco.subco:oldmodule”错误。有没有办法强制构建

Answer 1

看看Maven在执行什么：

Executing Maven:  -B -f /scratch/jenkins/workspace/subco/subco/pom.xml -amd -pl org.mainco.subco:oldmodule,org.mainco.subco:subco,org.mainco.subco:moduleB,org.mainco.subco:database,org.mainco.subco:moduleF,org.mainco.subco:moduleA,org.mainco.subco:moduleH,org.mainco.subco:newmodule,org.mainco.subco:session,org.mainco.subco:moduleA,org.mainco.subco:newmodule,org.mainco.subco:moduleB clean install -e -P qa -P cloudbees -DskipITs

在 -pl 部分是你的旧模块。当您告诉 Maven 使用父项目构建不再属于该项目的模块时，它会失败。

该命令是在哪里生成的？怀疑旧模块在您的 Maven 配置文件或 Jenkins 配置之一中。
