How to run different version of JFreeChart in eclipse?

Question

I am working on a project where I am trying to find some interaction between various bugs in JFreeChart project. However, for this I have to merge different files from different versions of JFreeChart and compile them as one project to see if there is some possible interaction between bugs. But I am finding it difficult to run multiple versions since different versions have compatibility with different java versions? Is there any way to do this?

You can have multiple version of JFreeChart on your system, but only one will be first in the classpath when you build (javac) or run (java) the application. Here's one approach, in outline:

1. Download a target release, e.g. jfreechart-1.0.19.zip.

2. Unzip the file: unzip jfreechart-1.0.19.zip.

3. Enter the directory: cd jfreechart-1.0.19.

4. Patch the source as desired, for example.

5. Build a new JAR: cd ant ; ant -f build-fx.xml all

6. Install in the IDE and test.
