Java build on rawhide
by Orion Poplawski 24 Feb '08

24 Feb '08

This seems new. I'm try to build plplot in rawhide and getting the following. This seems to be pointing to a pretty fundamental issue with the java install. This was working a bit ago. cd /scratch/orion/redhat/plplot-5.9.0/plplot-5.9.0/fedora/bindings/java && /usr/bin/javac -classpath /scratch/orion/redhat/plplot-5.9.0/plplot-5.9.0/fedora/bindings/java /scratch/orion/redhat/plplot-5.9.0/plplot-5.9.0/fedora/bindings/java/config.java -d /scratch/orion/redhat/plplot-5.9.0/plplot-5.9.0/fedora/bindings/java ---------- 1.

NullPointerException in autotools propaties page
by Shunichi Fuji 21 Feb '08

21 Feb '08

hi, i have got NullPointer error in project propaties page on autotools-plugins. in AutotoolsDefaultBuildDirHandler, sometimes AutotoolsDefaultBuildDirHandler("status") returned null. (it happen that didn't add configure to Used tools, didn't push apply button, when builder is autotools.) just aviod by continue. in MakeGenerator, at similler situation. when didn't apply tool-chain yet, but values are changed. then push ok to invoke this. if buildDir isn't null, return new Path(buildDir). otherwise return null. the caller of this function may handle by set to default build value. (at least in cdt-HEAD) i'm not sure this is a correct way from a design viewpoint. btw, i saw `FIXME: Use holder to set option value, not the "option" parameter`. it may be related? but i didnt see deeply yet. so i just put only a quick patch here. ### Eclipse Workspace Patch 1.0 #P com.redhat.eclipse.cdt.autotools Index: src/com/redhat/eclipse/cdt/autotools/AutotoolsDefaultBuildDirHandler.java =================================================================== RCS file: /cvs/eclipse/autotools/com.redhat.eclipse.cdt.autotools/src/com/redhat/eclipse/cdt/autotools/AutotoolsDefaultBuildDirHandler.java,v retrieving revision 1.4 diff -u -r1.4 AutotoolsDefaultBuildDirHandler.java --- src/com/redhat/eclipse/cdt/autotools/AutotoolsDefaultBuildDirHandler.java 30 Oct 2007 22:36:17 -0000 1.4 +++ src/com/redhat/eclipse/cdt/autotools/AutotoolsDefaultBuildDirHandler.java 20 Feb 2008 12:06:59 -0000 @@ -61,6 +61,7 @@ continue; } ITool tool = config.getToolFromOutputExtension("status"); //$NON-NLS-1$ + if (tool == null) continue; // We now want to get the builddir option for the tool.

Buildfile generation error occurred.. Not possible to generate Makefile and no existing Makefile found Build stopped.. So what is the problem

Orphaning packages
by Vivek Lakshmanan 09 Feb '08

09 Feb '08

Hello, I have been unable to provide necessary attention to a number of java packages I owned for the last little while, and I am afraid my schedule is only going to get tighter in the future. As a result I have orphaned the following packages: bea-stax byaccj classpathx-jaf classpathx-jaxp crytpix-asn1 isorelax jakarta-commons-collections jakarta-commons-pool java_cup jaxen jaxen-bootstrap jgroups jlex jzlib ldapjdk log4j regexp saxon saxon8 tanukiwrapper tomcat5 velocity xalan-j2 xmlrpc I apologize if any bugs you reported have not been acted upon recently. If some brave soul would like to take over, I can provide guidance, though it may be somewhat sporadic. Vivek

java code coverage tools
by Jack Tanner 07 Feb '08

07 Feb '08

As far as I can tell, this is the state of Java code coverage tools on Fedora 8... and it's not very good. If you know of something I'm missing, please chime in. Emma. [1] Development on the main tree seems to have stalled, but there seems to be active development around the Eclipse plugin [2]. There was an attempt to bring it into Fedora that failed [3], but it's listed as available from JPackage. [4] Cobertura. [5] Actively developed, no Eclipse plugin. Listed as available from JPackage. [6] TPTP. [7] Official Eclipse component. Not available in Fedora or JPackage.
