I use Groovy the same way as you use Java (importing the OJ classes).
I put groovy-all-1.7.0.jar (ca. 5 MB) into OpenJUMP's /lib directory and
develop OJ plugins with Eclipse (using the amazing Groovy-Eclipse Plugin,
NetBeans and IntelliJ IDEA). You can use Java classes in Groovy classes and
vice versa (Groovy files are compiled into .class files). Thus you can even
use Groovy classes from the BeanShell or Jython.
Since my two classes (mentioned previously) require Groovy Closures as
method parameters, it is necessary to call their methods within a groovy
file (these two classes are special cases).
Here is a HelloWorldPlugIn in Groovy:
<pre>
import com.vividsolutions.jump.workbench.plugin.AbstractPlugIn
import com.vividsolutions.jump.workbench.plugin.PlugInContext
import com.vividsolutions.jump.workbench.ui.plugin.FeatureInstaller
class HelloWorldPlugIn extends AbstractPlugIn {
void initialize(PlugInContext pluginContext) {}
boolean execute(PlugInContext pluginContext) {
def pluginPath = pluginContext.getWorkbenchContext().getWorkbench().
getPlugInManager().getPlugInDirectory().getAbsolutePath()
def htmlFrame = pluginContext.getWorkbenchFrame().getOutputFrame()
htmlFrame.setTitle("Hello, World!")
htmlFrame.createNewDocument()
htmlFrame.addText("Hello, World!")
htmlFrame.addText(pluginPath.toString())
htmlFrame.surface()
return true
}
}
</pre>
Another funny thing is, you can copy your Java code into a Groovy file and
it compiles.
