Subject: [PATCH] Upgrade Maven compiler source and target to 1.8
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hi,

While testing DevOps-Project-05 with the latest Jenkins Docker image and newer JDK versions, I noticed that the Maven build fails because the project is still configured with Java 7 source/target compatibility.

Error observed:

"Source option 7 is no longer supported. Use 8 or later."

Modern JDK versions no longer support compiling with source/target 1.7, so I have updated the Maven compiler configuration from Java 1.7 to Java 1.8.

Changes:
- Updated maven.compiler.source from 1.7 → 1.8
- Updated maven.compiler.target from 1.7 → 1.8

This keeps the project compatible with newer Jenkins + Docker environments while maintaining backward compatibility.

Tested with:
- Jenkins running in Docker
- Maven build: mvn clean install
- OpenJDK newer runtime

Build passes successfully after this change.

Thanks for maintaining this helpful DevOps learning repository!
