Hmm, this sounds like an Eclipse bug tickled by Ptolemy adjusting setting up the ptII/.classpath file.
I've seen stack traces inside eclipse 2.1.2. Rather than reinstalling, what I usually what I ended up doing was removing my eclipse/workspace directory and trying various things. You could try removing ptII/.classpath and seeing if the setup completes. That worked for me. I was able to build after hacking adding the following to .classpath.in: <classpathentry excluding="cm/" kind="src" path="ptolemy/copernicus/c/test"/> and I had to add ptolemy/copernicus/c/test/cm/| to the list of excluded files. At one point, the Java build path window came up and I had to remove jmf.jar and sound.jar I later removed the jxta jar files because they had this bogus ${PTII} inside of them. I'll fix configure momentarily. This bug occurred because our devel tree contains the jxta jar files, but we don't ship these jar files. To remove the jxta jar files, right click on the ptII project, select Properties -> Java Build Path -> Libraries You may later want to exclude ptolemy/moml/jxta from the build. Below is a copy of the .classpath.in that worked for me: --start-- <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry excluding="cm/" kind="src" path="ptolemy/copernicus/c/test"/> <classpathentry excluding="**/CVS/|**/codeDoc/|config/|doc/coding/templates/|ptolemy/apps/agilent/|ptolemy/apps/anytimecontrol/|ptolemy/apps/charon/|ptolemy/apps/crazyboard/|ptolemy/apps/etherealSting/|ptolemy/apps/fullscreen/|ptolemy/apps/giotto/|ptolemy/apps/ia/|ptolemy/apps/kurt/|ptolemy/apps/jmf/|ptolemy/apps/kvm/|ptolemy/apps/lego/|ptolemy/apps/lejos/|ptolemy/apps/midp/|ptolemy/apps/mobileCoding/|ptolemy/apps/pendulum/|ptolemy/apps/rijndael/|ptolemy/apps/robot/|ptolemy/apps/security/|ptolemy/apps/sobel/|ptolemy/apps/softwalls/|ptolemy/apps/soot/|ptolemy/apps/throttle/|ptolemy/apps/tini/|ptolemy/apps/transmission/|ptolemy/apps/vergil/|ptolemy/apps/waba/|ptolemy/apps/webstart/|ptolemy/apps/xsl/|ptolemy/copernicus/c/test/|ptolemy/copernicus/c/test/cm/|ptolemy/domains/ct/demo/Saber/|ptolemy/domains/gr/lib/experimental/|ptolemy/domains/pdf/|ptolemy/plot/servlet/|vendors/@ECLIPSE_EXCLUDING_SRC@" kind="src" path=""/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> @ECLIPSE_CLASSPATHENTRY_LIBS@ <classpathentry kind="output" path=""/> </classpath> --end-- I'll add a note to the website about this -Christopher -------- Thanks for your help, I also tried the method described but I can not get the project compiled, here is what I tried : tar xfz ptII3.0.2.src.tar.gz mv ptII3.0.2 ptII export PTII="/home/franck/bin/my_PTII/ptII" cd $PTII ./configure cd ~/bin/my_PTII eclipse& File->New Project Project Name : ptII Directory : /home/franck/bin/my_PTII Finish -->> An error occured while creating the java project Reason : invalid project description /home/franck/bin/my_PTII and /home/franck/bin/my_PTII/workspace overlap If I change the directory with : /home/franck/bin/my_PTII/ptII -->> An error occurred while creating the java project See error log for more details. (java.lang.NullPointerException in the .log of Eclipse !) I tried other thinks but I can only compile and run (make fast install) without Eclipse !
