有时候，我们并不希望 Jenkins Pipeline 因为某个特定错误而直接失败。
这时可以使用 catchError 来捕获错误，并将阶段（stage）或构建（build）结果更新为 SUCCESS、UNSTABLE 或 FAILURE（如果需要的话）。
Jenkinsfile 示例#
pipeline {
agent { node { label 'linux' } }
stages {
stage('Catch Error') {
steps {
catchError(buildResult: 'UNSTABLE', stageResult: 'UNSTABLE', message: 'abc: command not found') {
sh "abc"
}
}
}
}
}
Pipeline 输出示例#
17:14:07 [Pipeline] Start of Pipeline
17:14:08 [Pipeline] node
17:14:08 Running on linux in /agent/workspace/Stage-Job/catch-error
17:14:08 [Pipeline] {
17:14:08 [Pipeline] stage
17:14:08 [Pipeline] { (Catch Error)
17:14:08 [Pipeline] catchError
17:14:08 [Pipeline] {
17:14:08 [Pipeline] sh
17:14:08 + abc
17:14:08 /agent/workspace/Stage-Job/catch-error@tmp/durable-303b03ca/script.sh: line 1: abc: command not found
17:14:08 [Pipeline] }
17:14:08 ERROR: abc: command not found
17:14:08 ERROR: script returned exit code 127
17:14:08 [Pipeline] // catchError
17:14:08 [Pipeline] }
17:14:08 [Pipeline] // stage
17:14:08 [Pipeline] }
17:14:08 [Pipeline] // node
17:14:08 [Pipeline] End of Pipeline
17:14:08 Finished: UNSTABLE
