lets say i have 3 packages and a jar needs to be created for every package containing only the contents in the current package. My attempt is:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>first-jar</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>first-jar</classifier>
<excludes>
<exclude>/maven.task.3/src/main/java/third/ThirdMain.java
</exclude>
<exclude>/maven.task.3/src/main/java/second/SecondMain.java
</exclude>
</excludes>
</configuration>
</execution>
<execution>
<id>second-jar</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>second-jar</classifier>
<excludes>
<exclude>/maven.task.3/src/main/java/first/FirstMain.java
</exclude>
<exclude>/maven.task.3/src/main/java/third/ThirdMain.java
</exclude>
</excludes>
</configuration>
</execution>
</executions>
</plugin>
And this does indeed create different jars, however the content inside is the same, meaning the exclude clauses don't work. I tried excluding only the class(relative/absolute path) and only the package. Don't ask why i do this its for homework, it does not make a lot of sense! This is the way i attempt of doing it, if there is any other more efficient way please feel free to share it with me!
EDIT: Modular structure must not be used, it must be one single project.
Thanks in advance
It's already been answered in the comments but here's an example.
A parent pom:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.essexboy</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>jar1</module>
<module>jar2</module>
</modules>
</project>
And 2 child/modules poms, only the artifactId is different:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>parent</artifactId>
<groupId>com.essexboy</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>jar1</artifactId>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
</build>
</project>
Extra info
I created the parent with the command:
mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo.archetypes -DarchetypeArtifactId=pom-root -DarchetypeVersion=RELEASE
Then created 2 modules with the command
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=RELEASE
If you must have a single jar project (no modules and parent) you can do it with the shade-plugin:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.essexboy</groupId>
<artifactId>double-jar</artifactId>
<version>1.0-SNAPSHOT</version>
<name>double-jar</name>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.2.1</version>
<executions>
<execution>

@Esses Boy yes as i mentioned above, this is a much cleaner and easier approach, however i must do this using only one project and not modular structure.
@AlexVulchev I've updated the answer to show how to do it with the shade plugin, I'm sire there are other ways of doing it, but this works.
Why are you using shade-plugin and creating another time the jar's ? Based on the modules there will be created different jars for each module already....
@khmarbaise because of the previous comment that the questioner insists on doing it in single project, i.e. no modules. I agree with you it should be 2 modules.
