需求

Jenkins日志打印内容很长，或者并发编译导致，日志内容不容易查看。

对于具体业务失败， 开发者希望看到具体业务自身的日志内容。

解法

tee 命令能够保证， shell命令执行的内容，即往控制台输出，又往文件输出，满足了第一个要求，业务日志单独输出。

echo "ABCD" | tee temp.txt temp02.txt

将输出内容"ABCD"同时重定向到 temp.txt 和 temp02.txt 并且在终端打印输出

echo "ABCD" | tee -a temp.txt

将输出内容"ABCD"重定向追加到 temp.txt同时在终端打印输出

archiveArtifacts 指令

https://jenkins.io/doc/pipeline/tour/tests-and-artifacts/

When there are test failures, it is often useful to grab built artifacts from Jenkins for local analysis and investigation. This is made practical by Jenkins’s built-in support for storing "artifacts", files generated during the execution of the Pipeline.

This is easily done with the archiveArtifacts step and a file-globbing expression, as is demonstrated in the example below:

此指令可以将关注的文件，打包保存在Jenkins系统上，跟具体的构建关联起来。

Jenkinsfile (Scripted Pipeline)

node {

    try {

        stage('Test') {

            sh './gradlew check'

        }

    } finally {

        archiveArtifacts artifacts: 'build/libs/**/*.jar', fingerprint: true

        junit 'build/reports/**/*.xml'

    }

}
