Creating a jar from a maven project in intellij

Question

I created a new maven project in IntelliJ and set packaging to jar but when I build it, the target folder does not contain a jar. I\'m sure its something really dumb on my p

Answer 1

You should build you project using IDEA's Maven Projects view.

View -> Tool Windows -> Maven Projects

or open it from left bottom corner menu:

And then build your project with maven goals - i.e. package:

If packaging is set to jar in pom.xml, you will get a jar in target dir.

Answer 2

Assuming that the screen-shot shows the complete pom file, you are missing the entries that define the artifact. Try adding something like this following immediately after the tag:

  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.example</groupId>
  <artifactId>stackoverflow-question</artifactId>
  <version>0.0.1-SNAPSHOT</version>

You should end up with stackoverflow-question-0.0.1-SNAPSHOT.jar in your /target directory. You may need to refresh the directory to see it (You certainly have to in Eclipse)

Answer 3

Go to the maven project and double click clean and package.

For just do following:

Answer 4

You need to have "jar" in packaging section of your pom.xml. You can add this before dependencies section:

<packaging>**jar**</packaging>

Then go to View -> Tool Windows -> Maven and in Maven window expand everything and double click on "package" in Lifecycle section.

Answer 5

You need the maven jar plugin in order to create a jar

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <classpathPrefix>lib/</classpathPrefix>
                <mainClass>add your main class</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>
