Unable to Build using MAVEN ERROR Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:3.7.1:single No assembly descriptors found
Really a novice with this maven and pom.xml files stuff. We've got an older java program we are trying to up from 8 to 21 and having maven errors so I thought I'd step back and create a simple hello world app that can do a maven build and look at the differences in the pom.xml file to see if I can figure it out. That being said I can't even get the hello world app to do a maven build.
Pom.xml file:
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>simple-java21-maven</artifactId>
<version>1.0.0</version>
<properties>
<maven.compiler.source>21</maven.compiler.source>
<maven.compiler.target>21</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<build>
<plugins>
<!-- Compiler Plugin -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.11.0</version>
<configuration>
<release>21</release>
</configuration>
</plugin>
</plugins>
</build>
Most posts I've seen seem to point to the mismatched Java version reference or missing JAVA_HOME system variable and I have mine set to: JAVA_HOME=C:\Program Files\Java\jdk-21
Errors start with:
Error reading assemblies: No assembly descriptors found. at org.apache.maven.lifecycle.internal.MojoExecutor.doExecute2(MojoExecutor.java:333)
I don't know what this is referring to.
Java is not my primary programming language so all this configuration is pretty foreign to me.
Program works in Debug- just can't get the Maven build figured out.
I'm on a Windows 11 OS if that matters.
any help appreciated Just trying to build a simple jar file from a quick sample app.
Read more on this than I care to admit but I keep getting the same error.
