I have a project and i need to generate both jar and war of the project using same pom.xml.
So when i run 'mvn clean install' it should generate both jar and war in my ~/m2 directory.
I needed this jar to build my second project.
Below is the sample pom.xml.

<artifactId>demo-service</artifactId>
<name>demo-service</name>
<description>service demo</description>
<packaging>war</packaging>

You can try options archiveClasses and attachClasses of maven-war-plugin

So your configuration can look like:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-war-plugin</artifactId>
  <version>3.3.2</version>
  <configuration>
    <archiveClasses>true</archiveClasses>
    <attachClasses>true</attachClasses>
  </configuration>
</plugin>

You should also use maven-install-plugin

Try this:

<?xml version="1.0" encoding="UTF-8"?>
