Re: Error in maven-dependency:copy

Hi Brian,
You're right. In fact, I made a mistake by using the plugin twice in my pom.xml (I've just seen the second usage at the completely bottom of the pom.xml...bad) 

I've corrected and now it works perfectly.

Thanks for your help!

Allright then, this is what i'm doing so far...

If I type dependency:copy, I get this error:

What's missing then ?

Ok and this should work if you type mvn dependency:copy or mvn 
dependency:unpack. It's not bound to a phase in the pom so it won't run 
automatically.

Actually, I'm want to copy artifacts during the package phase and that's 
why I use the <executions> tag...However, both dependency:copy only and 
package execution throw the same error as previously.



Version is clearly 2.0-alpha-4; I just wanted to test copying junit 
artifact and put it into another directory, straightforward the example 
(http://maven.apache.org/plugins/maven-dependency-plugin/examples/copying-artifacts.html#Copying%20From%20the%20Command%20Line)

...but it still fails...

What does the error message mean ?

You're making progress. The message now says maven-dependency-plugin not 
dependency-maven-plugin like your first error. I suspect that your problem is 
now the same as described in the faq: 
http://maven.apache.org/plugins/maven-dependency-plugin/faq.html
Specifically, you must remove your configuration of the artifactItems from the 
<executions> tag. (the faq has a link to the proper configuration sample)

Hello Brian,

Thanks for helping but the problem still remains...

I've removed:
- all metadata files in /org/codehaus/mojo of my local repository ,

- maven-dependency-plugin and dependency-maven-plugin directories in 
/org/codehaus/mojo

- and also \org\apache\maven\plugins\maven-dependency-plugin


I'm also using maven-dependency-plugin version 2.0-alpha-4 as stated in 
my pom.xml and the error message below.


Do you have any others idea?


PS: I can't find any 2.0.7 version of maven-dependency-plugin, what do 
you mean by 2.0.7 ? Am I misunderstanding sth. about the management of 
this plugin version ?


Thanks,
Hervé

Somehow you are getting the old dependency-maven-plugin instead of the 
maven-dependency-plugin. Clear the /org/codehaus/mojo metadata from your local 
repo (and any internal proxies you have) and try again. This is already fixed 
for 2.0.7....doesn't help you now though ;-)

Hello,


I'm trying to copy some specific artifacts using the

I'm doing sth very simple and straightforward from what I've read from

but it simply does not work...

Error log & plugin usage are just below,
Am I missing something or are there any bugs in the plugin ?
