Ant Execute Java Program

Active7 years, 4 months ago

I've found examples on how to either set the classpath so that a Java program can be executed or to include external jars, but not both. My attempts to combine multiple examples in one file have failed.

  • Generating an Ant buildfile from a Java program sounds like a monumental task. I would try using an IDE first. As for you NPE in your Java program, I only know that you should use. The code was run in the java environment as follws javac ChapterAntProject.java.
  • Apache Ant Tutorial. This tutorial describes the usage of Ant as a build tool to compile Java code, pack this code into an executable jar and how to create Javadoc. The usage of Ant is demonstrated within Eclipse and from the command line. This tutorial is based on Apache Ant 1.8.x. The following demonstrates how to run a Java program.
  • Sample Ant Build File - JAR. You can use the java task to execute a class file as shown below. To clean and execute the program run the 'ant clean execute' command.

My source .java files are in the src directory, the file I want to execute is src/TEDI.java, the class files get put correctly into the build directory, and all my jars are in the directory jung2-2_0_1. Crash bandicoot ps1 download. I can get my program to compile, but not execute, using the following ant file:

When I run ant, it does the clean, create, and compile targets just fine, and then when it gets to execute it says: Could not find build/TEDI.class. Make sure you have it in your classpath Serial number lookup.

Anyway I'm hoping someone can tell me what I'm doing wrong in the path section. I added the pathelement bit after reading one example on how to create an ant target to execute a file, but it didn't help at all. There are a ton of examples and a lot of them do things differently to achieve the same thing (while none do exactly what I'm trying to do), so I can't figure out which way is correct for what I'm trying to do. Any help or ideas would be greatly appreciated.

Edit: Changed <pathelement location='${build}'/> to <pathelement location='${output}'/> as per Sandro's answer, but it doesn't change the error message at all.

I assume that this is a simple 'Hello, World' Java program (HelloWorld.java) and that the HelloWorld.java, build.xml and the HelloWorld.class (to be generated) are in the current directory (. HelloWorld.java file.

The java task expects a Java class name, not the path of a class file.So you should use
