Building the Weld JSF examples

[asookazian]

I recall having problems in the recent past and posting about it here about building the JSF examples in the Weld distro using maven (or possibly ant?).  The problem now with login app, for example, was that the 2.0.2-FCS JSF jar was not in the mvn repo and thus the dependency was not resolving.  So I had to manually add it to the local repo using mvn deploy:deploy-file as mvn so kindly instructs.  Well that takes a while.  The command looks like this:

C:\java\weld-1.0.1-Final\examples\jsf\login>mvn deploy:deploy-file -DgroupId=javax.faces -DartifactId=jsf-impl -Dversion=2.0.2-FCS -Dpackaging=jar -Dfile=C:\java\jboss-6.0.0.20100216-M2\server\default\deploy\jbossweb.sar\jsf-libs\jsf-impl.jar -Durl="file://C:\Documents and Settings\asookazian\.m2\repository"

and do it for both the jsf-api.jar and the jsf-impl.jar.  The build fails.

Then I just read the release notes for 1.0.1-final and lo and behold the easy way:

* If using Maven, some artifacts are only available in the JBoss Repository. To allow Weld to correctly function, add the JBoss Repository to Maven. Edit your ~/.m2/settings.xml, and add:

      <profile>
         <id>jboss.repository</id>
         <activation>
            <activeByDefault>true</activeByDefault>
         </activation>
         <repositories>
            <repository>
               <id>repository.jboss.org</id>
               <url>http://repository.jboss.org/maven2</url>
               <releases>
                  <enabled>true</enabled>
               </releases>
               <snapshots>
                  <enabled>false</enabled>
               </snapshots>
            </repository>
         </repositories>
      </profile>

So I did that, saved changes, opened a new cmd prompt in Windows XP and then try to build the numberguess example:

Anybody else seeing this???  Looks like JSF JARs not in classpath.  Is that b/c I did not set my JBOSS_HOME?  Note the SCM repo warning...

I noticed the instructions for build in the ref doc mostly discuss using ant, not maven...

Getting the same results (compilation failures) when I run 'ant'.  So what is wrong??

[asookazian]

Ok, so it would be good to actually view the build.xml.  It basically invokes two different maven lifecycle phases via the Maven macrodef in the parent build.xml (clean and install).

But this needs to be cleaned up as well, no?

<project basedir="." name="Numberguess Example Build" default="restart">
     
     <property name="example.name" value="weld-numberguess" />

     <import file="../../build.xml" />
     
   <target name="package">
      <maven target="install" basedir="${basedir}">
         <arg line="-Pjboss5" />
      </maven>
   </target>
   
   <target name="clean">
      <maven target="clean" basedir="${basedir}">
           <arg line="-Pjboss5" />
      </maven>
   </target>
     
</project>

The name of the example has been changed from weld-numberguess to numberguess so that property value above is incorrect.

Also, why is it hard-coding -Pjboss5 as an argument to the cmd line when invoking mvn?  What if we're using jboss6, do we simply have to override that manually by typing:

ant clean -Pjboss6

or similar or what?

Here's some more data via mvn help:active-profiles:

1) it would be nice if the output was specific as to which settings.xml is the source (typically there are two settings.xml files)
2) why is jboss5 an active profile?  most users will be using JBoss6 with Weld, no?

[asookazian]

Ok, so I was able to build se\hello-world and the ~/.m2/settings.xml changes is being picked up by Maven:

[INFO] Unable to find resource 'org.jboss.weld:weld-se:pom:1.0.1-Final' in repository repository.jboss.org (http://repository.jboss.org/maven2)
Downloading: http://repo1.maven.org/maven2/org/jboss/weld/weld-se/1.0.1-Final/weld-se-1.0.1-Final.pom

I guess I must have installed the wrong JSF 2.0.2-FCS JARs somehow...

[asookazian]

Yep, that was it.  The one I installed via mvn deploy:deploy-file goal execution had a package that started with com.foo.bar and this one starts with javax.foo.bar.  After I deleted the directories from my local mvn repo and then ran 'mvn clean install', I see this:

Downloading: http://repository.jboss.org/maven2/javax/faces/jsf-api/2.0.2-FCS/jsf-api-2.0.2-FCS.pom
395b downloaded  (jsf-api-2.0.2-FCS.pom)
Downloading: http://repository.jboss.org/maven2/javax/faces/jsf-api/2.0.2-FCS/jsf-api-2.0.2-FCS.jar
580K downloaded  (jsf-api-2.0.2-FCS.jar)

Also, it did not install the the 2.0.2-FCS jsf-impl.jar.

Wow, what a disaster.

I would recommend that the release-notes.txt located in the root of the Weld distro be noted in the readme.txt for each example, etc. or similar.

For dummies like me of course ;)

Or how bout adding the following xml snippet to the parent POM for the examples???  Then what happened to me can't happen again (or less likely)...

<profile>
         <id>jboss.repository</id>
         <activation>
            <activeByDefault>true</activeByDefault>
         </activation>
         <repositories>
            <repository>
               <id>repository.jboss.org</id>

               <snapshots>
                  <enabled>false</enabled>
               </snapshots>
            </repository>
         </repositories>
      </profile>

Now on to the JRebel 3 testing!!!

btw, this is still happening:

[INFO] Working directory: C:\java\weld-1.0.1-Final\examples\jsf\numberguess

We are working having all deps in Maven central so that this is not an issue in the future.
