I have below project structure. I wanted to prepare a jar with dependencies including different packages which has .java files.
Project Structure:
src/com/rev/automation/utilities
src/com/rev/automation/testdata
src/com/rev/automation/pages
Main Class:
org.openqa.selenium.remote
How to include "src/com/rev/automation" packages into the jar in maven? i'm preparing the jar using below code, But it is not including packages and files present in "src/com/rev/automation". Kindly suggest
<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>
<!-- MainClass in mainfest make a executable jar -->
<archive>
<manifest>
<mainClass>org.openqa.selenium.remote.RemoteWElement</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
While using Maven, you need to follow the Maven Standard Directory Structure.
In your case, create a folder structure like src/main/java and put all your code in java directory. So it should now look like src/main/java/com/rev/automation etc.
If you follow this structure, then your package will get included in the jar.
Update:
If you absolutely don't want to / cannot do what is mentioned above, alternatively, you can use the Maven Build Helper plugin. This will tell maven to include the specified directory as an additional source directory.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>src</source> // specify your directory here
...
</sources>
</configuration>
</execution>
</executions>
</plugin>

I have a code base which I want to distribute as jar. It also have dependency on external jars, which I want to bundle in the final jar.
I heard that this can be done using maven-assembly-plug-in, but I don't understand how. Could someone point me to some examples.
Right now, I'm using fat jar to bundle the final jar. I want to achieve the same thing using maven.
Note: If you are a spring-boot application, read the end of answer
Add following plugin to your pom.xml
The latest version can be found at
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>CHOOSE LATEST VERSION HERE</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>

<id>assemble-all</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
After configuring this plug-in, running mvn package will produce two jars: one containing just the project classes, and a second fat jar with all dependencies with the suffix "-jar-with-dependencies".
if you want correct classpath setup at runtime then also add following plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>fully.qualified.MainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
For spring boot application use just following plugin (choose appropriate version of it)
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
<mainClass>${start-class}</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
You can use the maven-shade-plugin.
After configuring the shade plugin in your build the command mvn package will create one single jar with all dependencies merged into it.
Maybe you want maven-shade-plugin, bundle dependencies, minimize unused code and hide external dependencies to avoid conflicts.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.1</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>

I had to add it to the maven-assembly-plugin in order to get that in the manifest
You can use the onejar-maven-plugin for packaging. Basically, it assembles your project and its dependencies in as one jar, including not just your project jar file, but also all external dependencies as a "jar of jars", e.g.
<build>
<plugins>
<plugin>
<groupId>com.jolira</groupId>
<artifactId>onejar-maven-plugin</artifactId>
<version>1.4.4</version>
<executions>
<execution>
<goals>
<goal>one-jar</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Note 1: Configuration options is available at the project home page.
Note 2: For one reason or the other, the onejar-maven-plugin project is not published at Maven Central. However jolira.com tracks the original project and publishes it to with the groupId com.jolira.
An alternative is to use the maven shade plugin to build an uber-jar.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version> Your Version Here </version>
<configuration>
<!-- put your configurations here -->
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
Read if you want to use the maven-assembly-plugin.
As other answers have already outlined, it seems that the maven-shade-plugin offers more features and is the recommended plugin to build a fat jar, but in case you would like to use the maven-assembly-plugin the following plugin configuration will work.
The answer of #jmj explains that the correct classpath can be setup with an additional maven-jar-plugin, but this will only add the classpath to the original jar and not the fat jar. The information must instead be directly included into the configuration section of the maven-assembly-plugin.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.4.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.package.YourMainClass</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>assemble-all</id>
<phase>package</phase>
<goals>
<goal>single</goal>

When you now run maven package, your normal and fat jar will be created and you can run your fat jar with java -jar yourJar.jar.
I have a JavaFx project which I want to reduce to one jar file.
My pom contains a java-fx plugin:
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.1.4</version>
<configuration>
<mainClass>application.Main</mainClass>
<jfxAppOutputDir>${project.build.directory}/jfx/app</jfxAppOutputDir>
</configuration>
<executions>
<execution>
<id>create-jfxjar</id>
<phase>package</phase>
<goals>
<goal>build-jar</goal>
</goals>
</execution>
</executions>
</plugin>
and an 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>
<!-- MainClass in mainfest make a executable jar -->
<archive>
<manifest>
<mainClass>application.Main</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>

</executions>

When I call "mvn package" a single jar file is being build but it does not contain the jfx-jar file but contains some sort of "jar wihout jfx support"-version.
How can I tell the Maven Assembly Plugin to use the jar version from the jfx plugin (which is located in jfxAppOutputDir (../jfx/app/))?
Found the problem myself.
the jar file with the "no main manifest attribute"-error was created by maven-jar-plugin. But it is possible to configure it to omit that creation. If you are interested please take a look:"what-is-the-best-way-to-avoid-maven-jar"
the assembly plugin worked correctly. It was my fault. I thought that the assembly plugin creates a jar file with all dependencies including all resource files(all files from the resource folder). My mistake. "jar-with-dependencies" includes all jars belonging to the project, nothing more.

When i build the component(Say 'component-war' using mvn clean install), i see the target(component-war) has a minified JavaScript.But Maven local repo does not contain the minified file.
Due to which when i package the project(Say 'project-ear') target does not contain the minified file.
I Also have the following configuration in my POM -
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<packagingIncludes>WEB-INF/lib/urlrewritefilter-*.jar,WEB-INF/lib/xercesImpl-*.jar,WEB-INF/lib/io-*.jar,WEB-INF/lib/xtags-*.jar,**/*.xml,**/*.xsd,**/*.pdf,**/*.txt,**/*px,**/*dummyfile,**/*.properties,**/*.class,**/*.png,**/*.css,**/*.js,**/*.jsp,**/*.jspf,**/*.xsl,**/*.html,**/*.htm,**/*.vm,**/*.tld,**/*.gif,**/readme,**/*.zip,**/*.jpg,**/*.zul,**/*.zs,**/*.eot,**/*.svg,**/*.ttf,**/*.woff,**/*.swf
</packagingIncludes>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
First you must delete:
<execution>
<id>crf</id>
<phase>package</phase>
because for WAR project in phase package maven-war-plugin has priority over other plugins (http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html#Plugins) - WAR is build before minification.
BTW, it explains why Maven has phase prepare-package and do not have post-package; everything defined in package is effectively post-package
That's not enough, because maven-war-plugin will overwrite minified files. You must configure it to ignore original JS files, because their minified versions are already prepared by minify plugin (Exclude source files from WAR package)
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<packagingIncludes>WEB-INF/lib/urlrewritefilter-*.jar,WEB-INF/lib/xercesImpl-*.jar,WEB-INF/lib/io-*.jar,WEB-INF/lib/xtags-*.jar,**/*.xml,**/*.xsd,**/*.pdf,**/*.txt,**/*px,**/*dummyfile,**/*.properties,**/*.class,**/*.png,**/*.css,**/*.js,**/*.jsp,**/*.jspf,**/*.xsl,**/*.html,**/*.htm,**/*.vm,**/*.tld,**/*.gif,**/readme,**/*.zip,**/*.jpg,**/*.zul,**/*.zs,**/*.eot,**/*.svg,**/*.ttf,**/*.woff,**/*.swf
</packagingIncludes>
<!--HERE **************** -->
<warSourceExcludes>crf/js/*.js</warSourceExcludes>
<!--HERE **************** -->
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
BTW, your maven war plugin configuration (packagingIncludes) suggests you have a mess in project. You should consider clean it up, because my proposal extends configuration and any further unnecessary extension cause whole configuration hard to understood
What is the easiest way to build spring boot jar file without its dependencies?
Basically I should be able to keep dependency jar files in a separate folder.
Currently I'm using spring boot maven plugin, however, it creates a Fat jar file with all dependencies.
Just do not use spring-boot-maven-plugin at all and use JAR packaging. This way the build wouldn't package dependencies into the JAR.
spring-boot-maven-plugin has option for repackaging that puts dependencies inside (making uber jar)
You can disable repackaging or make repackaged .jar go with other classifier [2]

http://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/repackage-classifier.html
Below is a solution I found on How to Create an Executable JAR with Maven,
You just need to put these in your plugins.

Replace change your build entry in pom.xml to

In the target folder there will be a dependency_jar folder with all the dependency jars, along with "project_name.jar"(fat jar) and "project_name.jar.original"(jar file of your code)
