Building a fat jar using maven
(7 answers)
Closed 1 year ago.
I'm trying to build a fat jar with maven assembly plugin for distributing a desktop application.
My POM looks like
<build>
<!-- To parse properties files under resources folder : -->
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.3.0</version>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>com.acme.qpguard.editor.Application</mainClass>
</manifest>
</archive>
</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>
</plugins>
</build>
The command mvn assembly: single is creating a fat jar with other dependencies, but fat jar does no include my classes.
So while starting the jar, I'm getting an error
Error: Could not find or load main class com.acme.qpguard.editor.Application
How can I fix my POM so that it includes my project files too
Please note that the project is running fine in Eclipse.

Thanks, #Mayur and #Randy Casburn. Your pointers definitely helped me in finding a fix using maven shaded plugin.
I'm posting the fix as someone may find this useful at a later point of time

<mainClass>com.acme.qpguard.editor.Application</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Note: I have to apply a filter for removing signature files from some jars as it was breaking the execution.

Maven corrupting binary files in src/main/resources when building jar

I've got an issue with a maven project where I am distributing dlls from the src/main/resources/lib folder.
The project is built as a single jar with dependencies using the maven-assembly-plugin.
Unfortunately, the maven process is corrupting my dll libraries during the copy process so that they are no longer useful to the application.
I've had a look at such concepts as resource filtering.
Here's my relevant pom.xml
Does anyone have any ideas?
I think I need to do something like this but so far it's not working for me.
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<resources>
<resource>
<directory>${basedir}/src/main/resources/lib</directory>
<filtering>false</filtering>
</resource>
</resources>
<archive>
<manifest>
<mainClass>de.bochumuniruhr.psy.bio.behaviourcoder.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
My final solution (based on the answers below):
Thank you for the great answers. I ended up going with the answer that doesn't require extending the configuration of the maven-resources-plugin. I placed my binary files in the src/main/resources/unfiltered-resources folder as I needed to filter my other resources.
Here is a link to the source code.
Below is my final working pom at the time of writing.
<build>
<finalName>BehaviourCoder_${git.build.time}_${git.commit.id.describe-short}</finalName>
<resources>
<resource>
<directory>${basedir}/src/main/resources</directory>
<filtering>true</filtering>
</resource>
<resource>
<directory>${basedir}/src/main/unfiltered-resources</directory>
<filtering>false</filtering>
</resource>
</resources>
<plugins>
<plugin>

</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>

<manifest>
<mainClass>de.bochumuniruhr.psy.bio.behaviourcoder.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
</plugins>
</build>

This part:
<resources>
<resource>
<directory>${basedir}/src/main/resources/lib</directory>
<filtering>false</filtering>
</resource>
</resources>
Should be under under the <build/> section like this:
<project>
<build>
<resources>
<resource>
<directory>${basedir}/src/main/resources/lib</directory>
<filtering>false</filtering>
</resource>
</resources>
<plugins>
...
</plugins>
</build>
</project>

When assembly plugin kicks in it is already too late, as the resources were already copied by maven resources plugin. You should exclude filtering on earlier phase (when the resources are being copied to target folder by maven resource plugin).
See maven's docs how to do this: https://maven.apache.org/plugins/maven-resources-plugin/examples/binaries-filtering.html
For your case this can be something like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>dll</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
</plugins>

Eclipse deletes files under WEB-INF on every run

I'm trying to setup Maven with my GWT project but every time that I start debugging, it deletes web.xml and other files that are required to start.
Code fragment related to build from my pom.xml :
<build>
<outputDirectory>${webappDirectory}/WEB-INF/classes</outputDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>

<configuration>
<webXml>${webappDirectory}/WEB-INF/web.xml</webXml>
<source>${target.jdk}</source>
<target>${target.jdk}</target>

Web.xml is not getting included in War using mvn plugin

I am trying to include web.xml in war.
Here is how my pom.xml looks like, I have added maven-resources-plugin and maven-war-plugin to pom
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<id>copy-web.xml</id>
<phase>process-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/war/WEB-INF</outputDirectory>
<resources>
<resource>
<directory>src/main/webapp/WEB-INF/</directory>
<filtering>true</filtering>
<includes>
<include>web.xml</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webXml>${basedir}/war/WEB-INF/web.xml</webXml>
</configuration>
</plugin>
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>2.3</version>
<configuration>
<filesets>
<fileset>
<directory>tomcat</directory>
</fileset>
<fileset>
<directory>war/WEB-INF/classes</directory>
</fileset>
<fileset>
<directory>war/WEB-INF/lib</directory>
</fileset>
</filesets>
</configuration>
</plugin>
But when I extract war here is what I get
/tomcat/work/Catalina/localhost/XProject/WEB-INF
/tomcat/work/Catalina/localhost/XProject/WEB-INF/classes
/tomcat/work/Catalina/localhost/XProject/WEB-INF/lib
What am I doing wrong ?

I have used multiple time maven-war-plugin. Here is the code snippet. This will include the web.xml if web.xml is present in your folder structure else ignore.
The problem which I think from your code snippet, may be issue with relative path for the web.xml. Use the below maven-war-plugin to resolve your issue
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>

Add the warsourcedirectory tag.
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<warSourceDirectory>WebContent</warSourceDirectory>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>

I have encountered the same problem while having the web.xml in the default path
src/main/webapp/WEB-INF/web.xml
but wasn't included in the .war.
Following #sitakant suggestion I removed the maven-resources-plugin from the pom.xml and web.xml is now included in the .war without further configurations.

Using war excludes in the pom.xml

The maven documentation for this has to be wrong.
Here are the various permutations I have tried with all failing to exclude the file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<warSourceExcludes>**/*server.properties</warSourceExcludes>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webResources>
<resource>
<!-- this is relative to the pom.xml directory -->
<directory>src/main/resources/com/mycom/myapplication/</directory>
<!-- there's no default value for this -->
<excludes>
<exclude>**/*server.properties</exclude>
</excludes>
</resource>
</webResources>
</configuration>
</plugin>
A mail list entry suggests using this older version and a string list:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.1</version>
<configuration>
<webResources>
<resource>
<!-- this is relative to the pom.xml directory -->
<directory>src/main/resources/com/pictage/provendirect/</directory>
<!-- there's no default value for this -->
<excludes>**/*server.properties</excludes>
</resource>
</webResources>
</configuration>
</plugin>
Which results in:
(found static expression: '/*server.properties' which may act as a default value).
Cause: Cannot assign configuration entry 'excludes' to 'interface java.util.List' from '/*server.properties', which is of type class java.lang.String
Also tried:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.1</version>
<configuration>
<packagingExcludes>
**/server.properties
</packagingExcludes>
</configuration>
</plugin>
Any ideas? I am going crazy with this.

A more careful reading of the maven docs suggests:
<configuration>
<webResources>
<resource>
should only be used when excluding resources outside /src/main/resources. To do it inside this folder, you need to use warSourceExcludes and possibly warSourceDirectory parameters if the property isn't in the root of the directory.
I cry a little inside when it takes me hours to to do something via configuration in maven when it could have been handled in two seconds with a scripting language but I guess it's the 'right' way to implement it.
