When I'm trying to build as jar with all dependencies using maven-assembly-plugin, I'm getting always the issue:

Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:3.1.1:single (make-assembly) on project testMods: Unable to parse configuration of mojo org.apache.maven.plugins:maven-assembly-plugin:3.1.1:single for parameter source: Cannot find 'source' in class org.apache.maven.archiver.MavenArchiveConfiguration

The same issue will be even if I change the version of maven-assembly-plugin using path:

\.m2\repository\org\apache\maven\plugins\maven-assembly-plugin

Deleting org folder using \.m2\repository\org path, didn't help to solve this issue. When maven reloaded all dependencies, I get the error: Unable to parse configuration of mojo again.

I've noticed that instead of getting single jar for all modules, I get separately two jars, but not single for all. During compiling, I get target-folders just for separated modules, but not for main POM.

If I delete in main POM:

<executions>
  <execution>
     <id>make-assembly</id>
     <phase>package</phase>
     <goals>
        <goal>single</goal>
     </goals>
  </execution>
</executions>

Then I don't see this error during packaging and compiling. And plugin works, but I'll get separated jars only like:

• checker-1.0-SNAPSHOT.jar
• TextInputProgram-1.0-SNAPSHOT.jar (in their own modules folders)

If I run one of them, I see:

no main manifest attribute, in D:\IdeaProject\testMods\testMods\checker\target\checker-1.0-SNAPSHOT.jar

But I generated in resource folder MANIFEST, as you can see my structure. To create it, I choosed these options in Project Structure -> Artifacts:

In addition, I tried to use in main POM maven-shade-plugin instead of maven-assembly-plugin. In this case I can compile and package, but again I have two different jars as separated modules like:

• original-TextInputProgram-1.0-SNAPSHOT.jar
• TextInputProgram-1.0-SNAPSHOT.jar
• checker-1.0-SNAPSHOT.jar
• original-checker-1.0-SNAPSHOT.jar

but not main jar that includes all of this.

Can somemone tell me what I need to correct here to get finally jar that includes all modules inside?

Answer 1

I did a build by removing following two lines

<source>11</source>
<target>11</target>

from maven-assembly-plugin plugin section of parent(testMods) pom, and the build was success.

As per the doc of assembly:single, there is no any tag called source or target defined as valid parameter, thus plugin fails with cannot find 'source'(the first invalid tag)
