为什么执行Shell脚本的Jenkins构建步骤将构建标记为失败？

我在詹金斯的工作中运行PMD。我的Shell脚本构建步骤如下

alias pmd="/root/pmd-bin-6.11.0/bin/run.sh pmd"
pmd -d "/var/jenkins_home/workspace/Warnings" -R rulesets/java/quickstart.xml -f xml > results.xml

生成的results.xml文件非常好。但是，在我的控制台日志中，它说

"Build step 'Execute shell' marked build as failure".

我不熟悉Bash/Linux/Shell脚本，所以请帮助我。谢谢

如果在生成时发现任何冲突，PMD将返回非零代码。您可以禁用此功能，并在分析结束时获得出口0，该出口将标记您的构建成功

请参见以下示例：

pmd -d "/var/jenkins_home/workspace/Warnings" -R rulesets/java/quickstart.xml -f xml -failOnViolation false> results.xml

有关更多信息，请查看文档。

詹金斯解释每个退货状态！=0表示批处理命令失败。在大多数情况下，这是一个很好的注解。例如，如果使用robocopy，成功复制文件将返回状态！=0-即使复制成功-因此Jenkins将生成标记为失败

您可以取消状态代码，或者让batch命令始终返回0，这样Jenkins会将您的构建标记为成功。post fix^&退出0将为您执行此操作

bat <execute your command here> ^& exit 0

你查过詹金斯的控制台日志了吗？它可以提示失败的原因。嗨@nos，我已经添加了控制台日志。
