That should have been java -jar blogger.com instead of java -jar "app".. The -jar option only works if the JAR file is an executable JAR file, which means it must have a manifest file with a Main-Class attribute in it.

I also tried extracting the jar to see if I could find the main class, but there are to many classes and none of them has the word "main" in it's name. There must be a way to fix this because the program runs fine on other systems. First, it's kind of weird, to see you run java -jar "app" and not java -jar app.
Where com. MyClass is the class holding the public static void main String[] args entry point. For Mavensomething like the following snippet should do the trick.
Note that this is only the plugin definition, not the full pom. SomeClass is the class that contains the main method to run the program. What that class is depends on the program, it's impossible to tell from the information you've supplied. In this example all the dependency jars as specified in section will be automatically included in your single jar.
Note that jar-with-dependencies should be literally put as, not to be replaced with the jar file names you want to include. MF file. The Main attribute is necessary to tell java which class it should use as the application's entry point. Wondering how you could look at what's inside a jar file? Open the jar file with WinRAR.
