#COMPILING JAVA PROGRAM WITH JAR CODE#
Here's the source code for that part of my build process:Īs you can see, this segment of code builds a variable named class.path based on all the jar and zip files that are in my project's lib folder.Compiling your Python code with jythonc May, 2003Īfter you make your. Some of these jar files can also be run as if they are a main program. For the purpose of completeness, I thought I better include the target I created that builds this classpath variable. If you navigate to the hello/ directory, you can compile Hello.java using the. I mentioned that earlier in my build script I created the variable named class.path. (This is a collection of images that are used by my application.) Here is the general procedure for creating an executable JAR: Compile your java code, generating all of the program's class files. When compiling, I set the classpath using the class.path variable, which I created earlier in my build script.Īfter the javac task executes successfully, I copy a bunch of image files from the src directory structure to the classes folder structure. jar cmf Hello.mf Hello.jar Hello.class Hello.java and run it by typing: java -jar Hello.jar The file Hello.jar can now be downloaded and executed. By convention, I named all my unit test classes this way, so I am able to exclude them in the compiling process. This task compiles all the files found in the src directory, excluding all files matching the naming patter Test*.java. The first part of the script runs the Ant javac task. Here's a brief description of what this Ant target does: Here's the source code for my Ant compile target: Step 2 - Need to save this java file in a folder with ' Demo.java ' and it can be saved in a folder. Step 1 - Need to create a java program either in Notepad or other IDE. This particular script happened to be used for building a Swing application, but it can really be used to build any Java application, command-line based or other. After successful installation of JDK in our system and set the path, we can able to compile and execute Java programs using the command prompt.

While I'm digging around through Ant build scripts today, here's a sample Ant target I created that demonstrates how to compile a Java program, while also showing a few other things, including how to exclude your JUnit tests during the compile process.
