+ | Bug #: 2137 Product: Ant |
+ | Status: NEW Version: 1.3 |
+ | Resolution: Platform: PC |
+ | Severity: Major OS/Version: Windows NT/2K |
+ | Priority: Other Component: Optional Tasks |

+ +============================================================================+
+ | DESCRIPTION |
+ VAJAntToolGUI properties are evaluated the first run but not thereafter.
+
+ To reproduce,
+
+ Create a task that updates a property. For example, a task that reports a
+ random number each time it's run. I know this seems of little value but it's
a
+ simple test case.
+
+ Here�s a simple build.xml file
+
+ <project name="simple" default="testReload" basedir=".">
+ <target name="testReload" description="qshow up">
+ <taskdef name="makeRandom" classname="com.test.RndNumber"/>
+ <makeRandom randomProperty="rnd.number"/>
+ <echo message="say number = ${rnd.number}"/>
+ </target>
+ </project>
+
+ See the end of this bug report for the Task code.
+
+ Load a build.xml file with the VAJ GUI tool. Build testReload. Note the rnd
+ number is displayed. Click Build repeatedly.
+
+ If you change the Message Level on the ANT GUI to debug. You'll see the
+ property being set. See below:
+
+ testReload:
+ [echo] say number = 3
+ BUILD SUCCESSFUL
+ Total time: 0 seconds
+
+ testReload:
+ [echo] say number = 3
+ BUILD SUCCESSFUL
+ Total time: 0 seconds
+
+ <<<<<<<<debug message level on here>>>>>>>
+
+ Build sequence for target `testReload' is [testReload]
+ Complete build sequence is [testReload]
+ +User task: makeRandom com.test.RndNumber
+ Setting project property: rnd.number -> 68
+ [echo] say number = 3
+ BUILD SUCCESSFUL
+ Total time: 0 seconds
+
