Eclipse settings ---------------- The following files should be excluded from build output: *.metaprops See Preferences/Java/Building/Output Folder/Filtered Resources Eclipse.classpath ----------------- [This has been tested with Eclipse 3.2. It may not work with other versions.] The file eclipse.classpath is intended as a starter .classpath file for building JMeter using Eclipse version 3. Note that Eclipse does not handle RMI compilations, nor is it easy to use for creating jar files. However, it is easy to use Eclipse to run Ant. The following targets may prove useful: compile-rmi - compiles the RMI files that Eclipse ignores package-only - creates the jars package - compiles everything and then packages it run_gui - compiles, packages, and then start the JMeter GUI from the jars Invoking Ant targets inside Eclipse ---------------------------------- You can use the "Run As --> Ant Build" and select target, or you can use the "Windows->Show View->Ant View". Then select the "build.xml" file and drag and drop to the "Ant View". Now you can invoke targets by clicking on them. Note that if you invoke for example the "compile" target, and get error messages about " Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK " it just means that your Eclipse project is set up with JRE libraries instead of JDK libraries. The suggested fix is to add a JDK in "Window->Preferences->Java->Installed JREs". Then do a "Project->Properties" and select "Java Build Path" in the left pane, and then select the "Libraries" tab in the right pane. Scroll to the bottom, select the "JRE System Library", and click "Remove". Then click "Add library..." , select "JRE System Library", and then select the JDK. Now it should work when you invoke the "compile" target. Finishing the build using Ant ----------------------------- Find the build.xml file in the project, right click on it, and click "Run As --> Ant Build". Make sure you select the "package" target. This will compile any remaining classes (e.g. the RMI ones), and then create all the jars. Now refresh the project (you should add this to the Ant build properties) Launching from Eclipse ---------------------- You can use the Ant target run_gui to run the JMeter GUI, or you can follow the instructions below to add a Java Application launch, which will for example, allow you to use the debugger to run JMeter. These instructions assume you have configured Eclipse to use the classpath as suggested in eclipse.classpath, and have run "ant package" to compile the RMI classes and build the jars. Create a new Java Application launch configuration. On the Main tab, enter the following as the main class: org.apache.jmeter.NewDriver On the Arguments tab, in the Working Directory area, pick the radio button next to "Other" and enter the following in the text box: ${workspace_loc}/jmeterproject/bin where "jmeterproject" is the name of the JMeter project. [It would be nicer to use ${project_loc}/bin but unfortunately the Eclipse Debug view does not seem to preserve any of the project variables]
