Subject Re: Ant 1.7.0 can't find Junit in ${user.home}/.ant/lib
Date Fri, 09 Feb 2007 09:34:02 GMT
I have tested with JDK 1.3 and it works:
~/learning/a/junit> ant -debug
Apache Ant version 1.7.0 compiled on December 13 2006
Buildfile: build.xml
Adding reference: ant.PropertyHelper
Detected Java version: 1.3 in: /usr/java/jdk1.3.1_18/jre
Detected OS: Linux
Adding reference: ant.ComponentHelper
Setting ro project property: ant.file -> /home/reilly/learning/a/junit/build.xml
Adding reference: ant.projectHelper
Adding reference: ant.parsing.context
Adding reference: ant.targets
parsing buildfile /home/reilly/learning/a/junit/build.xml with URI =
file:///home/reilly/learning/a/junit/build.xml
Project base dir set to: /home/reilly/learning/a/junit
 +Target:
 +Target: -check.junit.exists
 +Target: -check.junit
 +Target: build.something
Attempting to create object of type org.apache.tools.ant.helper.DefaultExecutor
Adding reference: ant.executor
Build sequence for target(s) `build.something' is
[-check.junit.exists, -check.junit, build.something]
Complete build sequence is [-check.junit.exists, -check.junit,
build.something, ]

-check.junit.exists:
[antlib:org.apache.tools.ant] Could not load definitions from resource
org/apache/tools/ant/antlib.xml. It could not be found.
Setting project property: junit.exists -> true

-check.junit:
Skipped because property 'junit.exists' set.

build.something:

BUILD SUCCESSFUL
Total time: 0 seconds


Are you running on windows?
If so there may be the usual problems with spaces and
perhaps the location of user.home.
