[jira] Created: (MWAR-187) regression running war packaging with maven 2.1

regression running war packaging with maven 2.1
-----------------------------------------------

                 Key: MWAR-187
                 URL: http://jira.codehaus.org/browse/MWAR-187
             Project: Maven 2.x WAR Plugin
          Issue Type: Bug
    Affects Versions: 2.1-beta-1
         Environment: Apache Maven 2.1.0 (r755702; 2009-03-18 20:10:27+0100)
Java version: 1.6.0_11
Java home: D:\platina\java\jdk6\jre
Default locale: fr_FR, platform encoding: Cp1252
OS name: "windows xp" version: "5.1" arch: "x86" Family: "windows"
            Reporter: nicolas de loof
            Priority: Minor


Using plugin version 2.1-beta-1, my webapp can't get packaged.
It can be fixed by downgrading the plugin to 2.0.2

Hendy Irawan commented on MWAR-187:
-----------------------------------

Downgrading to war-plugin 2.0.2 didn't solve the problem for me, it gave me yet another problem by including bad dependencies in WEB-INF/lib. (i.e., some "provided" dependencies such as el-api and jsp-api were included).

I downgraded to war-plugin 2.1-alpha-2 which solved the problem, the most recent version that worked for my case.

Pablo commented on MWAR-187:
----------------------------

I tried to downgrade to 2.0.2 but I encountered this issue: MWAR-134
Downgrading to 2.0 fixed my problem.
(I can provide an example project if needed.)

Pablo updated MWAR-187:
-----------------------

    Attachment: MWAR-187-bad_webapp_cache.zip

Please have a look at the project {{MWAR-187-bad_webapp_cache.zip}}.
I'm not really sure how this badly formatted {{webapp-cache.xml}} file (i.e. containing a {{modelEncoding}} node) ended up in my target folder, but this was the cause of my problem.

Here is how to reproduce the problem with Maven 2.1.0:
* Run {{mvn install}} and the exception described above will occur.
* Run {{mvn clean install}} and the packaging will work fine (because the target folder containing the badly formatted file will be deleted)

Pablo commented on MWAR-187:
----------------------------

I know what JIRA is, thanks.
My aim was just to provide a test case for this issue (as good JIRA users usually do), not to ask for help as a newbie would do in a forum.

Are you sure that "NOTHING" is the appropriate word?
Forcing the plugin version to 2.1-beta-1, the stack trace is EXACTLY the same as the one provided in the description (feel free to do a diff).

--------------------------------------

One way to quickly work around this issue is to deactivate the cache.

{code:xml}
<configuration>

Pablo commented on MWAR-187:
----------------------------

Cleaning or disabling cache are workarounds, but I think it would be a good thing anyway to catch this runtime exception.

I see two places where you could do this.
Either:
* In {{WebappStructureSerializer.fromXml}}, catch silently the {{XStreamException}} and return null.
Then, {{AbstractWarMojo.buildWebapp}} will work properly, behaving as the "no cache" mode.

or:
* In {{AbstractWarMojo.buildWebapp}}, catch the {{XStreamException}} and branch to the "no cache" mode.
