[Xmltask-users] Adding contents to a buffer accross several invocations

[Holger Rauch]

Hi,

I'm trying to add (insert) several XML fragments into the same buffer, but
accross multiple <xmltask> invocations like this:

1st invocation:

<xmltask destbuffer="esbcglobalsetup">
  <insert path="/"><![CDATA[<project name="repconf" 
basedir="."></project>]]></insert>
</xmltask>

2nd, etc. invocation(s):

<xmltask destbuffer="esbcglobalsetup">
  <insert path="/project"
          expandProperties="true"><![CDATA[<property name="user.target.country" 
value="${user.target.country}" />]]></insert>
  <insert path="/project"
          expandProperties="true"><![CDATA[<property name="country.abbrev" 
value="${country.abbrev}" />]]></insert>
  <insert path="/project"
          expandProperties="true"><![CDATA[<property name="aviation.authority" 
value="${aviation.authority}" />]]></insert>
</xmltask>

Printing the buffer after the final addition and making Ant fail on purpose:

<xmltask>
  <print buffer="esbcglobalsetup" comment="Contents of esbcglobalsetup" />
</xmltask>

<fail message="*** Failing on purpose ***" />

BUILD FAILED
/home/hrauch/eap-trunk-new/EmpicSuite-trunk/build-scripts/common-includes/common-global-setup.xml:225:
null

(line 225 is the beginning of the 2nd <insert> fragment).

Any hints why this happens and how I can work around it?

Any info/pointers on the above issue will be appreciated.

Kind regards,

        Holger
