- try catch
引言
Jenkins pipeline 脚本，有时因某些异常而中断执行，导致整个 pipeline job 都失败。为了整个 Job 能继续运行，我们需要处理某些异常。
try catch
当在 Jenkins Pipeline 中使用 try-catch 块时，即使某个阶段失败，后续的阶段也会继续执行。下面是一个示例，演示了一个阶段失败但不影响后续阶段的运行：
pipeline {agent anystages {stage('Example') {steps {script {try {// 模拟一个可能抛出异常的操作def result = 10 / 0 // 这里会抛出除以零的异常echo "Result: $result" // 这行不会执行} catch (Exception e) {echo "Exception caught: ${e.getMessage()}"// 在这里可以处理异常，比如记录日志、发送通知等currentBuild.result = 'SUCCESS' // 将当前构建标记为成功}}}}stage('Next Stage') {steps {echo "This stage will still run even if the previous stage fails"}}}
}
Pipeline 执行 log，在这个示例中，Example 阶段中的操作会导致除以零的异常，但是我们在 catch 块中处理了异常，并将当前构建标记为成功（currentBuild.result = ‘SUCCESS’）。因此，即使 Example 阶段失败，Next Stage 阶段仍会继续执行。
19:20:11 [Pipeline] {
19:20:11 [Pipeline] stage
19:20:11 [Pipeline] { (Example)
19:20:11 [Pipeline] script
19:20:11 [Pipeline] {
19:20:11 [Pipeline] echo
19:20:11 Exception caught: Division by zero
19:20:11 [Pipeline] }
19:20:11 [Pipeline] // script
19:20:11 [Pipeline] }
19:20:11 [Pipeline] // stage
19:20:11 [Pipeline] stage
19:20:11 [Pipeline] { (Next Stage)
19:20:11 [Pipeline] echo
19:20:11 This stage will still run even if the previous stage fails
19:20:11 [Pipeline] }
19:20:11 [Pipeline] // stage
19:20:11 [Pipeline] }
19:20:11 [Pipeline] // node
19:20:11 [Pipeline] End of Pipeline
19:20:11 Finished: SUCCESS
