I just made a new DrJava development release. You can download
drjava-20090402-r4864 from SourceForge.
The latest feature I’ve added is automatic update, which enhances the “Help/Check for New Version” dialog we’ve had for a while. If DrJava detects that there is a newer version available on SourceForge, then it gives the user the choice of an automatic update or a manual download.
For the automatic update, DrJava determines from where on the user’s computer it was started from and what kind of file it was (*.jar, *.exe or a Mac DrJava.app). It then downloads the corresponding file from the newest release. To actually replace the existing file, DrJava now starts a helper process in the temporary directory and shuts down. The helper copies the downloaded file onto the old file (if possible) and then starts the new version, which deletes the helper files in the temp directory.
By default, this is done once a week, but only beta and stable releases are suggested. The user can change the frequency, though, and also change the dialog to consider development releases.
Of course I would like you all to try this feature out on your computers. However, because the new version will not detect itself as a new version and you probably don’t want to wait until we make the next release, I have made a simulator available that always detects a new version.
Please download and execute that simulator, go to the “Help” menu and select “Check for New Version”. Make sure that the combo box says “Check for: all versions” so you download the latest developer version, not the latest stable version. Then click on “Automatic Update”. DrJava should then display a progress dialog as it downloads, potentially ask you if you want to quit, and then restart, as if nothing had happened. But now
you have the latest version!
Please let me know how this is working on your systems. I am looking forward to your comments and questions.
