Is there a reason why you are avoiding invoking the main class like java -cp /usr/local/jar/foobar.jar:/some/other/path.jar com.your.main.classname ? This type of invocation allows you to mix absolute paths with relative paths. Put this into a shell script or batch file to avoid having to actually type or remember the full classpath to simplify things.
Starting a groovy script with #!/usr/bin/env groovy has a very important limitation – No additional arguments can be added. No classpath can be configured, no running groovy with defines or in debug. This is not a groovy issue, but a limitation in how the shebang (#!) works – all additional arguments are treated as single … Read more
The executable Jar file format only allows you to specify one main class. In order for you to be able to execute different applications, you’ll need to either create a “manager” as you suggest, or to use the classpath instead: java -cp myjar.jar MyClass However, this approach will ignore the classpath you have configured in … Read more
maven-jar-plugin: This plugin provides the capability to build and sign JARs. But it just compiles the java files under src/main/java and src/main/resources/. It doesn’t include the dependencies JAR files. maven-assembly-plugin: This plugin extracts all dependency JARs into raw classes and groups them together. It can also be used to build an executable JAR by specifying … Read more

You can include a third party jar inside your bundle by adding the third party jar to the root directory of the bundle jar file and then adding a bundle classpath header to the bundle’s manifest, e.g.: Bundle-ClassPath: .,my3rdparty.jar If you want to place third party jar to subdirectory, specify the path without using heading … Read more
You can do : 1) javac -cp /path/to/jar/file Myprogram.java 2) java -cp .:/path/to/jar/file Myprogram So, lets suppose your current working directory in terminal is src/Report/ javac -cp src/external/myfile.jar Reporter.java java -cp .:src/external/myfile.jar Reporter Take a look here to setup Classpath
A JRE directory has a bin/java.exe. You can run a jar from that JRE simply with <path_to_jre>/bin/java.exe -jar Executable.jar If you don’t want to have to open a console each time, simply put the above line in a .bat file and double click on that.
This will happen when you doubleclick a JAR file in Windows explorer, but the JAR is by itself actually not an executable JAR. A real executable JAR should have at least a class with a main() method and have it referenced in MANIFEST.MF. In Eclispe, you need to export the project as Runnable JAR file … Read more
