Maven war:init - throws exception

[Graham Leggett <mi...@sharp.fm>]

Hi all,

I am trying to figure out some of the mavel goals, one of which is the 
building of a war file.

I tried out war:init, expecting to see some kind of output about 
directories it needs, and where I should put things to create a war file.

Initially maven tried to download some dependancies. My link is 
downright aweful, and some of the downloads timed out. I had to ^C the 
process and try again. It seems though that maven has not handled the 
download process properly - it did not try to resume downloads on the 
partially downloaded files, or notice that some of the jar files were 
not complete.

Eventually the dependancies were either down or broken, and maven bombed 
out with an exception. I then tried to delete the contents of the 
repository directory, thinking that things might return to a sane state. 
Maven now bombs out with a different exception:

java.lang.ClassNotFoundException: xml
	at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:186)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:299)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:255)
	at org.apache.commons.jelly.parser.XMLParser.createTag(XMLParser.java:1039)
	at 
org.apache.commons.jelly.parser.XMLParser.startElement(XMLParser.java:647)
...

So far maven does not look to be very stable at all. Is this the case? 
Should I be considering the use of maven for my project, or is it too 
early in development to be considered useful?

Anyone know how to get maven back to a sane state?

Regards,
Graham

Deleting maven and reinstalling it fixed the issues I was having - 
however maven really should be more robust when downloading files. At 
the moment it does not do anything special to a half downloaded file - 
it assumes it's downloaded, and then bombs out when it tries to unpack 
the jar.

To make Maven sane, just install it again.  It's not worth trying to 
debug what you've done to it.  Follow the install instructions you used 
the first time. If that doesn't work, post to the list again.

As to the plugins, try the documentation first, then the mailing list 
archives
http://maven.apache.org/reference/plugins/index.html


Cheers,

Ben
