I can now run my simple application using this command line command, that adds all JAR files to the classpath for the JVM: The JAR files are downloaded to the target/dependency directory: This will instruct Maven to analyze the pom.xml file, find the direct dependencies, find the associated JAR files, determine the indirect dependencies for each of these direct dependencies and process them similarly and recursively. Before the operation, here is the application. Using a simple Maven instruction, all JAR files are gathered and copied to a designated directory. To find all these JAR-files manually is not simple: it may not be so simple to determine which files are required, the files may not be easy to locate and the indirect dependencies (stemming from the JAR files that the application directly depends on) are almost impossible to determine. The number of JAR files required to eventually run the generated class is substantially. Take the dependencies in this pom.xml file (for a Java application that will work with Kafka Streams): #Maven exe file download download#In order to help out with all run time dependencies, Maven also can download all jar-files for the direct and even the indirect dependencies. Maven uses these dependencies during compilation – to have all direct dependent classes available for the compiler. The Maven pom.xml file is where these dependencies are described. With a few simple XML elements, I can indicate which libraries my application has a direct dependency on. Maven is a great mechanism for describing the dependencies of a project. class file that is result of compiling my Java code, I need a large number of JAR-files. To run the class, all indirectly invoked classes should also be available. In order to compile the class, all directly referenced classes from supporting libraries should be available. In order to run my simple class locally I need to: My challenge is simple: I am creating a small Java application – single class with main method – that has many direct and indirect dependencies.
