I am trying to create an executable jar with dependencies packaged. So far I have been receiving the "no main manifest attribute". Does anyone knows what I am doing wrong?
In the top of the POM I have added the packaging jar
<groupId>com.moga</groupId>
<artifactId>capacityplanfacilities</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
Here is my 2 tested approaches (Maven Shade and Apache Maven Assembly) according to the documentation:
<build>
<!-- <sourceDirectory>${basedir}/src/main/java</sourceDirectory>-->
<!-- <testSourceDirectory>${basedir}/src/test/java</testSourceDirectory>-->
<outputDirectory>${basedir}/target/classes</outputDirectory>
<!-- Do not work for when running tests-->
<!-- <testOutputDirectory>${basedir}/target/test-classes</testOutputDirectory>-->
<pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>

Many thanks
The issue was solving by modyfying the path of the manifest. I tested the built in generation of the Manifest file in the Intellij and discovered that the issue was probably related to the location of the Manifest, I was addying to the same level as the pom, whereas intellij set in the java folder.
