Could I bind an antlib to a xmlns via ?

[Ja...@rzf.fin-nrw.de]

I created an antlib for a bundle of tasks/macrodefs. Including via
    <project xmlns:ccm="antlib:...">
works, but then 
- I have to add the antlib to the global Ant installation
(%ANT_HOME%/lib; %USER_HOME%/.ant/lib)
  which means the build is not reliable after a checkout on a clean
machine [1] or
- modify the start command (ant.bat; %ANT_OPTS%;
%USER_HOME%/ant_{pre|post}.bat) which makes
  that machine different from the other in the team.

I would prefer having the antlib in the project directory and bind the
antlib with the given
classpath inside the buildfile.




  <typedef resource="antlib:..." uri="ccm"
classpath="../../build/antlib.jar"/>
  <ccm:start user="${user}" pwd="${pwd}" database="${db}"/>
this results in
  The prefix "ccm" for element "ccm:start" is not bound.

I think this is because the error occurs while parsing and the <taskdef>
would be executed after that.

Does anyone see a possibility to load the antlib from inside the
buildfile?

Hi Jan,

You are forgetting to bind the xmlns namespace to a URI.


<project xmlns:example="antlib:a.b.c" .../>
    <taskdef resource="a/b/c/antlib.xml"
             uri="antlib:a.b.c"
                    classpath="jars/example.jar"/>
      <example:hello/>
