I'm trying to compile derby 10.3.1.4 and I'm continuing having this error on build
BUILD FAILED /paulo/svn/10.3/build.xml:335: The following error occurred while executing this line: /paulo/svn/10.3/java/engine/org/apache/derby/loc/build.xml:36: taskdef A class needed by class org.apache.derbyBuild.MessageBuilder cannot be found: org/apache/tools/ant/Task I have code from svn https://svn.apache.org/repos/asf/db/derby/code/branches/10.3 575672 and also svn https://svn.apache.org/repos/asf/db/derby/code/trunk 575674 First run of "ant " worked fine but second run turns this error. Then i run "ant clean"and then again first ok, second not. I'm able to start server but not sure if everything went well. I can't use ./bin/.. scripts, But always derbynet.jar not found at $LOCALCLASSPATH. I'm able to compile derbyNet.jar and configure $CLASSPATH and $LOCALCLASSPATH. But to start server i need to do manually. I didn't install osgi.jar and SR 169 jars. Also i'm not using Java1.6.x I'm missing something? PJ
