The problem with version 2.6 is that the Maven’s folder structure does not conform to Wicket’s folder structure. This seems to be fixed in version 2.7. Alternatively, you can use Maven-eclipse-plugin version 2.5.1.
In short: If your
pom.xml file contains
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.6</version> </plugin>
replace it with this
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.5.1</version> </plugin>
For the past few days I was wondering why Maven’s install gave me a Heap Overflow exception on JUnit tests on some of my machines. I tried increasing the memory by using the environment variable MAVEN_OPTS, by passing the option “-Xmx512m” to the JVM through Eclipse and from the command line. All to no avail.
Then I found this blog entry by Keith Chapman. And it worked! Here’s the solution in short:
The JUnit tests ignore the environment variable MAVEN_OPTS. You have to tell Maven’s surefire plugin to increase memory. Add this to your pom.xml file:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <forkMode>pertest</forkMode> <argLine>-Xms512m -Xmx512m</argLine> <testFailureIgnore>false</testFailureIgnore> <skip>false</skip> </configuration> </plugin>
The upgrade from the Ubuntu 8.04 LTS version to 9.04 (codename “Jaunty Jackalone” = JJ) was very smooth. It did NOT screw up the X-Server, SMB, Cups, NFS, SSH, USB, etc. For me it was about a 3GB download.
The first thing I noticed was that a nasty gdm-login-screen-resolution bug was fixed by upgrading from 8.04 to 8.10.
Since each upgrade changes the default version of ones most used/favorite software, I will list those products I was concerned about most:
Sun Java (http://java.sun.com/)
- OK: JJ comes with the current Java JRE and SDK version (1.6_13)
- Out-of-date: JJ comes with version 3.2 (2 years old). The current version is 3.4 (Ganymede). But since you can run Eclipse directly without compiling, this is no big deal.
GNU Emacs (http://www.gnu.org/software/emacs/)
- GNU Emacs snapshot (=bleeding edge/developer version): OK: installing emacs-snapshot-gtk gives a current developer version (build from 2009-04-05)
- Emacs stable: Out-of-date: The current Emacs version is 22.3. JJ has Emacs version 22.2, although Emacs 22.3 was released 2008/09.
- Out-of-date: JJ comes with AUCTeX version 11.84. Version 11.85 was released 2008/02. I’ll have to install this manually.
- OK: JJ has 2.9.0. The current version is 2.9.0.
- Out-of-date: JJ comes with texlive-2007… Just download the current texlive-2008 from the texlive homepage and install it beside the Ubuntu texlive version.
Skype-Plugin for Pidgin’s Instant Messenger
- I’ve already written a blog on some of the nice Pidgin features. After upgrading to JJ and seeing that Pidgin is used for internal messaging within Ubuntu, I am even more convinced that this is currently THE multi-protocol multi-plattform instant messenger to go with. Get the skype-plugin from http://eion.robbmob.com/ and install the Debian/Ubuntu skype4pidgin.deb file by executing “sudo dpkg -i skype4pidgin.deb”
- Not present in JJ’s repositories. I’m very sad about this, because to my knowledge this is the only software for managing a CD/DVD collection which does not require a database. Although its user interface (Tck/Tk) is not-so-stylish-up-to-date, it has many features which I have grown accostumed to and which are lacking even in current high-end Disk-Manager programs.
Pidgin is one of the many multi-protocol instant messengers. And its available for many plattforms (Windows, GNU/Linux, Mac OS X, etc). Although pidgin supports many protocols out-of-the-box (f. ex. ICQ, AIM, IRC, XMPP/Jabber, Groupwise), new plugins are constantly emerging. The Pidgin-Plugin page gives a nice summary.
Some additional plugins I’ve come across are:
