Hi James,

I'm on your Udemy Jenkins lecture.

I encountered the following error while building the first Jenkins project. Would you please kindly advise the next steps? Thank you!

I had the same problem and still did not get a solution. Did you get any?

The issue is related to the compilation failure due to source and target compatibility levels. However, in the webapp.xml provided, there is no Maven Compiler Plugin configuration similar to the server-side pom.xml.

FIXED the compilation issue, we can add the Maven Compiler Plugin configuration to the webapp module's pom.xml. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

4.0.0 com.example.maven-project maven-project 1.0-SNAPSHOT ../pom.xml webapp war Webapp Webapp. ${project.artifactId} org.apache.maven.plugins maven-compiler-plugin 3.8.1 7 7 org.mortbay.jetty jetty-maven-plugin javax.servlet servlet-api provided javax.servlet.jsp jsp-api provided

Ensure that we replace 7 with the appropriate source and target compatibility levels we want to use. After updating the pom.xml, save the changes and rebuild your project in Jenkins. This should resolve the source and target compatibility level errors for the webapp module.
