jelly variables scope

[jan_bar <he...@yahoo.com>]

Hi,

what is the scope of variable in Jelly script? For instance, I want to skip
JUnit tests in cacuts:test, is the following Jelly correct?

<!-- skip JUnit tests during cactus test -->
<preGoal name="cactus:test">
<j:set var="maven.test.skip.old-value" value="${maven.test.skip}" />
<j:set var="cactus.test.skip.old-value" value="${cactus.test.skip}" />
<j:set var="maven.test.skip" value="true" />
<j:set var="cactus.test.skip" value="false" />
</preGoal>

<postGoal name="cactus:test">
<j:set var="maven.test.skip" value="${maven.test.skip.old-value}" />
<j:set var="cactus.test.skip" value="${cactus.test.skip.old-value}" />
</postGoal>

Couple of questions:
* do I need to store/restore the values of variables or, when the goal
exits, all variables will be reverted to previous state?
* should I delete the temp variables with <j:remove>?
* maybe <j:scope> will handle this better?

Thanks, Jan

PS: Unfortunately, there is almost no documentation besides
http://jakarta.apache.org/commons/jelly/tags.html.

Variables are not automatically reverted after a goal to their previous state.

> * should I delete the temp variables with <j:remove>?
Only if you want to get rid of them.

Nope, the scope tag introduces a new scope for it's body only. This
would be hard to write in xml and still have the goal tags in the
right place.
