Trying to build a project in .jar using Maven. Here is my pom.xml :

 <?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.dugin.rostislav</groupId> <artifactId>OSLoaderServer</artifactId> <name>OSLoaderServer</name> <version>1.0 alpha</version> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.1</version> <configuration> <archive> <manifest> <addClasspath>true</addClasspath> <mainClass>com.dugin.rostislav.Main</mainClass> <packageName>com.dugin.rostislav</packageName> <addClasspath>true</addClasspath> <classpathPrefix>lib/</classpathPrefix> </manifest> </archive> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.4</version> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <includeScope>compile</includeScope> <outputDirectory>${project.build.directory}/lib</outputDirectory> </configuration> </execution> </executions> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>com.googlecode.json-simple</groupId> <artifactId>json-simple</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>io.undertow</groupId> <artifactId>undertow-core</artifactId> <version>1.3.25.Final</version> </dependency> <dependency> <groupId>io.undertow</groupId> <artifactId>undertow-servlet</artifactId> <version>1.4.8.Final</version> </dependency> <dependency> <groupId>com.j256.ormlite</groupId> <artifactId>ormlite-core</artifactId> <version>4.47</version> </dependency> <dependency> <groupId>com.j256.ormlite</groupId> <artifactId>ormlite-jdbc</artifactId> <version>4.47</version> </dependency> <dependency> <groupId>org.xerial</groupId> <artifactId>sqlite-jdbc</artifactId> <version>3.8.11.2</version> </dependency> <dependency> <groupId>javax.interceptor</groupId> <artifactId>javax.interceptor-api</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>net.lingala.zip4j</groupId> <artifactId>zip4j</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.8</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.google.code.findbugs</groupId> <artifactId>jsr305</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>com.google.inject</groupId> <artifactId>guice</artifactId> <version>4.0</version> </dependency> </dependencies> </project>

But, as a result, I get a 170 kb .jar'nik exclusively with my compiled classes and without the lib folder (although in the manifest this folder is mentioned).

What am I doing wrong and how to compile an executable .jar archive containing all the dependencies?

  • Use assembly plugin . - Sergey Gornostaev
  • Do you want everything to be in the same jar or your jar + lib folder with other jar-nicknames? - Sergey

Add the following config:

 <build> <plugins> … <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>package.MainClass</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> … </plugins> </build>

  • If you only need to collect all the dependencies in one jar, you can remove the maven-jar-plugin and maven-dependency-plugin. - Mikhailov Valentine
