Hello Fábio,
Could you have installed a JRE instead of installing a JDK on your build
agent?
Can you please:
- Add the following instruction in your Jenkinsfile just before the
invocation sh "mvn..." (1):
- sh "which java"
- sh "which javac"
- Re run the pipeline
- Share the Jenkinsfile you use?
- share the build logs with us
Note that if "which javac" fails then your problem is that you have
installed a JRE when Maven requires a JDK.
- A solution is to install a jdk on CentOS "sudo yum install
java-1.8.0-openjdk-devel". See http://openjdk.java.net/install/
- An alternative is to install a JDK through Jenkins Tool Installer

stages {
stage ("Build") {
steps {
git "https://github.com/cyrille-leclerc/my-jar.git";
withMaven(maven:"maven-3.5.2") {
writeFile file: '.archive-jenkins-maven-event-spy-logs', text:
''
sh "which java"
sh "which javac"
sh "mvn clean deploy"
}
}
}
}
}
