exec:java problem
Hi all,
i am new to maven2. i got some problem when i tried to follow the sample
program of the book "Maven: The Definitive Guide"
http://www.sonatype.com/books/maven-book/reference/customizing-sect-custom-exec.html
i can sucessfully build the the program by the mvn install command
http://www.codetter.com/snippets/l
but when i run the mvn exec:java
-Dexec.mainClass=org.sonatype.mavenbook.weather.Main, there is an exception
http://www.codetter.com/snippets/n
i have no idea about that exception. and does it related to the warning in
mvn:install about the MS950 encoding?
Thanks very much for your help.
Regards,
Kit

The warning you get is fairly standard. It happens when you don't
declare the character set encoding that you want to use for the copying
of resources. This probably has nothing to do with your error.
The error is indicating that the class
org.sonatype.mavenbook.weather.Main does not exist. Check the
"target/classes" directory under the project and see if that class
exists there. If not, then something either went wrong with the build
or you managed to delete your binary classes before running the code.

The solution is to add the proxy in the YahooRetriever.java
System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyPort", <port>);
System.getProperties().put("proxyHost", <proxy_host>);

it works in windows now.
the problem is previously, i created the maven project directly in eclipse
by the m2eclipse plugin and the project is located in the workspace.
then i try to create the project in the maven repository by the mvn
archetype:create and them import the project to the eclipse. it works fine
now.
but i can only retrieve the weather info once.
http://xml.weather.yahoo.com/ns/rss/1.0 doesn't work now...
anyway, the program works.
thanks very much for your help. =)

kit

Did you check to make sure that the class was in the target/classes
directory?
The UTF-8 encoding is normal on Linux. That's the default encoding when
one is not specified.
