version: ant-1.5.2-26 (the one that comes with release iso's of fedora core 2) I downloaded JBother, which is a jabber client. I ran ant on build.xml file, and it gave compile errors complaining it can not find some classes (e.g. JText, classes in swing package) that are already in J2SDK. (version 1.4.02) These packages that the java compiler complained about not finding are already in j2sdk libraries (I opened src.zip from j2sdk, and verified that they are there, we are talking about basic swing components, javax.sound classes ) then I went and downloaded ant 1.6 from the apache website it worked fine. Also I ran it with the 1.5 version that I got from the apache website, and it was also working. The best way to reproduce: the address for JBother (an open source app) http://linuxhelp.homeunix.com/cgi-bin/rblh/index.rb?handler=downloads&d=jbother and using the cvs commands, download the source: CVS Access You can download the latest development snapshot via anonymous CVS. Type: cvs -d ":pserver:anonymous@valhalla.dydns.com:/usr/local/cvs" login Just hit enter when it ask for a password. Then type: cvs -d ":pserver:anonymous@valhalla.dydns.com:/usr/local/cvs" co JBother To download the latest source. go into directory and type ant. If you have fedora core installed ant (the rpm) it will give errors about not finding j2sdk base classes. go and download from ant.apache.org site, set ant_home etc. it works fine.
I think this is a bug with the gcj-compiled version of ant that is in /usr/bin/ant in FC2. Problem will go away if one relinks classic-ant to be ant: su - cd /usr/bin mv ant gcj-ant ln -s classic-ant ant Behavior when compiling jmol source (www.jmol.org) is the same as reported above. Random classes in javax.swing.text are reported as missing in the import statements. If you rearrange the import statements then the *missing* classes change/move around. My platform is amd64. At first I thought it was a problem with sun jdk-1.5.0-rc-linux-amd64. But I found the same problem with j2sdk-1.4.2 ... the 32 bit version. Relink as above and your problem will go away. Miguel
Sounds like the problem is caused by missing classes. I'm going to defer this, since a) you have a workaround, and b) ant will be arranged differently in FC3.
