I am using maven assembly plugin to package a fat jar, and then I want to put the fat jar into the tar.gz package, which is also generated by mvn-assembly plugin.
The thing is assembly will not put the fat jar into the tar file, but put the small jar,which only contains code and no dependencies in it.
Here's my pom file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.5.5</version>
<configuration>
<descriptor>src/main/resources-local/assembly.xml</descriptor>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>my.App</mainClass>
</manifest>
</archive>
<outputDirectory>output</outputDirectory>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
And assembly.xml:
<id>release</id>
<formats>
<format>tar.gz</format>
</formats>
<dependencySets>
<dependencySet>
<outputDirectory>/lib</outputDirectory>
<includes>
<include>*:project:*:*</include>
</includes>
<useProjectArtifact>true</useProjectArtifact>
<unpack>false</unpack>
<scope>runtime</scope>
</dependencySet>
</dependencySets>

I have used maven assemble plugin to generate executable jar with dependencies.
I am trying to run the jar and getting Error: Could not find or load main class.
I have tried with and also tried option to specify classes folder.
Here is my pom.xml
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.abc.TestApplication</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
Try to use configuration block inside of an execution one:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>
com.abc.TestApplication
</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
I have a mvn built jar, which is working fine inside the target folder.
But if I copy the jar to different folder/machine.I get a class not found exception. I understand the jar is unable to access the dependencies. how can i fix this?
my pom contains,
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>

</goals>
<configuration>
<configuration>
<!-- exclude junit, we need runtime dependency only -->
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.outputDirectory}/dependency/

</configuration>
</configuration>

</executions>

Thanks In Advance,

Make a fat jar with dependencies using maven-assembly-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
The target folder would have additional jar-with-dependencies.jar; you should be able to use this anywhere.
I removed the maven jar and dependency plugins from my pom. Added
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.importer.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<finalName>xyz</finalName>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance
merges -->
<phase>package</phase> <!-- bind to the packaging phase
-->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
This created a jar with dependencies which can be executed anywhere. Also with the specific jar name.
I've tried to avoid the maven warning message which comes from assembly plug in (I compile 2 jar files which are compiled from the same module)
Part of my pom.xml :
maven-jar-plugin
2.3.1
default-jar
none
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>

</plugin>
</plugins>
During the compilation process I'm getting the next WARNING msg :
[WARNING] Artifact com.my.company:UAT-Mock:jar:jar-with-dependencies:1.0 already attached to project, ignoring duplicate
What should I add to pom.xml in order to avoid the warning ?
Thanks
Just add <attach>false</attach> to the configuration of both executions
My maven project has several dependent jars, but when I create a jar of my project I would like to include a subset of those dependencies. Is there a way to do this? Currently, I am using the pom.xml below (from question How can I create an executable JAR with dependencies using Maven?), but it is packaging every dependency with my project.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Try:
<dependencySets>
<dependencySet>
....
<excludes>
<exclude>commons-lang:commons-lang</exclude>
<exclude>log4j:log4j</exclude>
</excludes>
</dependencySet>
....
</dependencySets>
See Including and Excluding Artifacts for more details
Here is a snippet from my pom file.
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptors>
<descriptor>src/main/config/a.xml</descriptor>
<descriptor>src/main/config/b.xml</descriptor>

<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>attached</goal>
</goals>
</execution>
</executions>
</plugin>
I would like descriptor b.xml to depend on what a.xml generates (a jar with included dependencies).
Is this possible? How would I specify this in my b.xml descriptor?
Use two executions, one for a.xml and then one for b.xml.
