In general, with Java 1.6+ you should be able to use something like:
javac -cp /path/to/ImageJ/ij.jar:/path/to/ImageJ/plugins/* My_Plugin.java
You may run into trouble if you have JAR dependencies in subfolders of
plugins, but if your build configuration is getting that complicated I
suggest you keep ij.jar somewhere as a separate dependency and build
everything totally outside the ImageJ directory structure. That's how we
build the LOCI plugins.
