Let's verify if the method can extract the class names from our example JAR file through a unit test method: private static final String JAR_PATH = 'example-jar/stripe-0.0.1-SNAPSHOT. When I put this line in a file and run it from the same folder (using terminal or double-click in finder), I get 'Unable to access jarfile. jar file folder): java -jar './myjavatest.jar'. The following command works from terminal (from the. Let's have a look at how to extract class names from our example JAR file using the JarFile and JarEntry classes: public static Set getClassNamesFromJarFile(File givenFile) throws IOException – We take each class jarEntry, and change the path of the class file into the qualified class name, for example change “package1/package2/SomeType.class” into “” I'm trying to write a script that runs a.
To achieve our objective, we need to scan the JAR file from a Java program and get the class names. In this case, the command-line output isn't enough. However, sometimes we want to load some classes from a JAR file in our Java program. Using the jar command to print the class names from a JAR file is pretty straightforward.
