RE: [Subclipse-users] scope of revisionProperty from status in svn-ant task

Should be. "update" not "second", sorry, missed changing that when I changed
the example.

    <antcall target="update"/>

Hi Douglas.

Disclaimer: I learned this from the ant user lists so I had exactly the same
problem, so I haven't just made it up. :P

This is an issue with ant property visibility. It has nothing to do with
svnant.

A property is usually only visible within the "target" it was created a-la a
local variable.

However, if multiple targets are used in the starting call to ant, then all
properties created within those targets are visible to the other targets
called.

Given the ant script:

<target name="build">

    <antcall target="second"/>

    <echo>${repos.version}</echo> <!-- will display blank! -->

</target>

<target name="update">

   <svn .... property="repos.version"/>

</target>

If you instigate ant with "ant build", then repos.version is ONLY visible
in "second". "build" cannot access it even after making the antcall to
"update".

However, if you instigate ant with "ant update build", then repos.revision
IS visible to "build".

I had to change my starting scripts (in cruise control) to call "update
unit_test" rather than just "unit_test" which used to call update itself.

Hope it helps.

Regards,

Greg.

Subject: [Subclipse-users] scope of revisionProperty from status in svn-ant
task

I wish to set an ant property with the number of the revision so I can later

use it in a propset. Weirdly, the scope of the variable only seems to be

_outside_ the <svn> element.

<svn username="user1" password="user1password" javahl="true">

          <copy
srcUrl="https://myserver/svn/repos/connectfour/trunk"

 
destUrl="https://myserver/svn/repos/connectfour/branch-${branch-number}"

                   message="Branch-${branch-number} created" />

          <checkout url=""https://myserver/svn/repos/connectfour/trunk"

                   destPath="connectfour" />

          <status path="connectfour/README.txt"
revisionProperty="status.revision" />

<propset path="connectfour" name="subclipse:tags"

value="${status.revision},connectfour-${branch-number},/connectfour-${branch
-number},branch" />

...

</svn>

<echo message="Status Revision: ${status.revision}" />

Now, in the propset, the ${status.revision} is evaluated as an empty string,

but once the echo is reached, the number is output. I then suspected this

weird inverse scope problem and changed the script to:

<svn username="user1" password="user1password" javahl="true">

          <copy
srcUrl="https://myserver/svn/repos/connectfour/trunk"

 
destUrl="https://myserver/svn/repos/connectfour/branch-${branch-number}"

                   message="Branch-${branch-number} created" />

          <checkout url=""https://myserver/svn/repos/connectfour/trunk"

                   destPath="connectfour" />

          <status path="connectfour" revisionProperty="status.revision" />

</svn>

<svn username="user1" password="user1password" javahl="true">

<propset path="connectfour" name="subclipse:tags"

value="${status.revision},connectfour-${branch-number},/connectfour-${branch
-number},branch" />

...

</svn>

<echo message="Status Revision: ${status.revision}" />

and in that case, the variable in the second svn block in propset get read

perfectly.

That seems....odd, to say the least. Any ideas? This seems like a bug to me.

CCing replies to me would be great, I promise, on my third svn ant problem

I'll join the list. :-)

Cheers.

Douglas
