how to install jenkins and how to run pom xml through jenkins

Comments

Are you trying to install Jenkins on windows or ubuntu?

Answer 1

The complete process to install Jenkins can be summarized in five steps:

1. Install Java Version 8
2. Install Apache Tomcat Version 9
3. Download Jenkins war File
4. Deploy Jenkins war File
5. Install required plugins

For a detailed explanation, have a look at this blog.

To execute a pom.xml file through jenkins:

Go to Manage -> Configure System 

In the build section you'll find an option for adding your pom.xml file. Add the path of your pom.xml file and then apply and save.

Build the project and it'll use your project-oriented model configurations. 

example:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://ma... http://maven.apache.org/xsd/maven-4.0.0.xsd">

               <target>${jdk.level}</target>
            </configuration>
         </plugin>
         <!-- Added Surefire Plugin configuration to execute tests -->

dose jenkins's JDK override pom's JDK?

---

No, it doesn't instead you will encounter an error as shown below in the case of version mismatch.

Failed to execute goal org.apache.maven.plugins

Proper solution is to add needed JDK to Jenkins global configuration and then to specifically choose needed JDK version/installation under the project build configuration.
