Summary: Tasks defined with an antlib within a jar in succeeds
with Ant 1.7.1 and fails with 1.8.2
Product: Ant
Version: 1.8.2
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Core
AssignedTo: [email protected]
ReportedBy: [email protected]
Here is the project build.xml:
<?xml version="1.0" encoding="utf-8"?>
<project name="build" default="all" xmlns:test="antlib:com.test.tools.ant">
<typedef resource="com/test/tools/ant/extensions.xml" />
<typedef uri="antlib:com.test.tools.ant"
resource="com/test/tools/ant/extensions.xml"/>
<test:importProjectDefinition/>
<echo message="${test}"/>
</project>
Here is a properties file to be imported that resides in the same directory as
the build.xml. It contains:
<project name="properties">
<property name="test" value="test_value"/>
</project>
test.jar contains an antlib in extensions.xml:
<?xml version="1.0"?>
<antlib xmlns:current="ant:current" xmlns:test="antlib:com.test.tools.ant">
<macrodef name="importProjectDefinition">
<sequential>
<import file="${basedir}\properties.xml" />
</sequential>
</macrodef>
</antlib>
When you build on Windows the project fails with the following traceback when
attempting the import. The import only fails when the antlib is inside of a
jar. In the debugger it appears that the file in the jar does not exist and
the code then tests for a URL
(C:\EclipseDevelopment\test_4_head\test_case\script/properties.xml) which of
course would be malformed as a URL. The same build fails on linux with a
similar traceback. Here is the relevant section of the Windows log:
[import] java.net.MalformedURLException: unknown protocol: c
