Why is it so hard to do this in Java? If you want to have any kind of module system you need to be able to load jars dynamically. I'm told there's a way of doing it by writing your own ClassLoader, but that's a lot of work for something that should (in my mind at least) be as easy as calling a method with a jar file as its argument.. Any suggestions for simple code that does this?
$ mvn … #maven #javadoc #jar 4.0.1 (06 August 2020) com.needhamsoftware.unojar Single jar packaging based on a JarClassLoader. Unlike maven shade and gradle shadow, this form of packaging does not intermix classes into a single directory, and thereby maintains a degree of separation between libraries with distinct licensing concerns. JCL is also available in Maven Central Repository, which makes it very easy to use in maven projects as a dependency. h1. JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams.
A JarClassLoader is compiled that enables class files to load from jar files embedded inside of a jar file A main wrapper is generated that calls either the main-class indicated by the jar file generated by the maven-jar-plugin, or a main-class specified in the configuration of the exec-jar-plugin’s execution Uno-Jar. Uno-Jar provides single executable jar ("fat-jar") packaging based on a JarClassLoader. Unlike maven shade and gradle shadow, this form of packaging does not intermix classes into a single directory, and thereby maintains a degree of separation between libraries with distinct licensing concerns. Single jar packaging based on a JarClassLoader.

Using Maven to build executable JAR. How to use with Maven. The description Using Maven to build executable JAR on the original web site is valid only if you have the JarClassLoader copied into your project. When using it as an external Maven artifact, we additionally need to make sure that.
In the following query, we ask for all JarClassLoader (these are the ones which dynamically load Visual Rules generated rule model code from the database, and show the name of the rule model and the persistent ID if the JAR archive in the database.
A JarClassLoader is compiled that enables class files to load from jar files embedded inside of a jar file A main wrapper is generated that calls either the main-class indicated by the jar file generated by the maven-jar-plugin, or a main-class specified in the configuration of the exec-jar-plugin’s execution A JarClassLoader is compiled that enables class files to load from jar files embedded inside of a jar file A main wrapper is generated that calls either the main-class indicated by the jar file generated by the maven-jar-plugin, or a main-class specified in the configuration of the exec-jar-plugin’s execution The class ClassLoader is an abstract class. Given the binary name of a class, a class loader should attempt to locate or generate data that constitutes a definition for the class. A typical strategy is to transform the name into a file name and then read a "class file" of that name from a file system. Maven is being used for project management instead of ANT; JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs Notice how the JarClassLoader keeps track of where classes came from: for example the com.a.A class is contained inside the lib/a.jar file inside myapp.jar. At this stage you should be asking "How does One-JAR decide which is the main class?".
The URLs can refer either to directories or to JAR files.

In this tutorial, we will show you how to use Maven build tool, One-JAR plugin to create a single Jar together with its dependency Jars into a single executable Jar file, so called fat Jar. Tools used : Maven 3.1.1; JDK 1.7; Joda-time 2.5; 1. Create a simple Java project. Create a Java project from the Maven quick start template. Single jar packaging based on a JarClassLoader. Unlike maven shade and gradle shadow, this form of packaging does not intermix classes into a single directory, and thereby maintains a degree of separation between libraries with distinct licensing concerns.
The URLs can refer either to directories or to JAR files. 1. System Classloader.

It loads classes from different resources. Java ClassLoader is used to load the classes at run time. JarClassLoader is an implementation of the java.lang.ClassLoader that is able to load jars from within other jars. That means you can bundle your application and librarys within one jar and this class-loader will load all these jar-files.

This classloader contains core Maven runtime classes like MavenProject, AsbtractMojo and so on. This is the classloader set as the “container realm” in the Plexus container instance unless Maven Extensions classloader is created (see below). Maven could not find or load main class. Maven Error: Could not find or load main class, Unless you need the 'maven-assembly-plugin' for reasons other than setting the mainClass, you could use the 'maven-jar-plugin' plugin.
