My simplest and always working solution is copy the entire project’s dependencies to a pre-defined folder, and define the dependency classpath in the jar’s manifest file.īelow is the updated and final pom.xml, to use maven-dependency-plugin to copy all dependencies to target/dependency-jars/ folder, and use maven-jar-plugin to add the dependency classpath. The one-jar solution is really good, but I don’t like the custom class loader and fat-jar concept. Right-click the pom.xml file in your Maven project, select Run As, and choose a basic goal. Maven will put compiled Java classes into the 'target/classes' folder.
#Maven install pom file code#
By convention: Java source code is to be meant to live in the '/src/main/java' folder. In MyEclipse, running Maven commands can be done directly from a context menu. Apart from a pom.xml file, you also need Java source code for Maven to do its magic, whenever you are calling mvn clean install.
#Maven install pom file how to#
– Try one-jar plugin, it will create a fat-jar, which includes the entire project’s dependencies into a single jar file, read this article – Create a fat Jar file with Maven If you have used Maven, you are probably familiar with basic goals and phases and how to call them from the command line, e.g.
This hack is workable in project with less dependencies only, for large project with many dependencies, it will cause Java class name conflict issue. – Alternatively, use maven-assembly-plugin to extract all dependency jars into raw classes, and group it together. – You can put both log4j.jar and jodatime.jar inside the final.jar, but your classes are unable to call other classes which is inside the unpack log4j.jar, Java jar is designed like this, unless you create a special class loader like one-jar plugin.
#Maven install pom file update#
Update the generated App.java with the following content :Ĥ.1. The following files and folder structure will be created.Ībove folder structure is not enough, create a log4j.properties file and put it in src/main/resources/log4j.properties, just create the resources folder manually. DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false When you change the pom. In the pom.xml file, add a dependency you need. When IntelliJ IDEA imports the added dependency, it parses the dependency and updates your project. $ mvn archetype:generate -DgroupId= -DartifactId=dateUtils You can import dependencies to your Maven project. In this tutorial, we will show you how to use Maven build tool, to create a single executable Jar, and how to deal with the project’s dependencies.Ĭreate a Java project from the Maven quick start template.
