Try Roo Example Error

**akutz** · Jan 31st, 2011, 01:08 PM

I cannot seem to get the "Try Roo" example to build. I'm not new to Maven, so perhaps one of my global repositories or my own profile is screwing things up, but as I follow the example I finally receive the error as a result of the very last step "perform tests".

Code:

I'm running Maven 3.0 on OS X 10.6.6 using the latest Apple-provided version of Java.

Code:

Apache Maven 3.0 (r1004208; 2010-10-04 06:50:56-0500)
Java version: 1.6.0_22
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.6.6" arch: "x86_64" Family: "mac"

Should I switch back to Maven 2.2.1 perhaps? I know Eclipse has been using an embedded version of Maven for a long time (or rather the M2 project has), so I can't imagine that Roo lacks Maven 3 support.

Thank you for your help!

I had to disable "https" on the JBOSS repository. Using Maven 3 it still fails with the following errors:

http://paste.ideaslabs.com/show/QuPsx6kN60

Please tell me I'm doing something wrong. I can't believe that such a simple example is so plagued with bugs. If all Roo beginners experience these issues at the outset it's unimaginable that there would be any users left.

**akutz** · Jan 31st, 2011, 03:48 PM

So, I created the second problem by disabling JBOSS's SSL connection. If you tell the POM to access the JBOSS repo via http you'll actually get these files in place of the POMs:

Code:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>302 Found</title>
</head><body>
<h1>Found</h1>
<p>The document has moved <a href="https://repository.jboss.org/nexus/content/repositories/releases/org/hibernate/hibernate-core/3.6.0.Final/hibernate-core-3.6.0.Final.pom">here</a>.</p>
<hr>
<address>Apache Server at repository.jboss.org Port 80</address>
</body></html>

Clearly this is not correct.

So I need to:

1. Remove the invalid, cached artifacts from my repo.
2. Still figure out how to get Maven to talk to the JBOSS repo over SSL.

Please help!

**akutz** · Jan 31st, 2011, 05:26 PM

I can write a quick Java app:

Code:

import java.io.*;
import java.net.*;

public class Foo
{

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception
    {
        String s;
        BufferedReader r =
            new BufferedReader(new InputStreamReader(
                new URL("https://repository.jboss.org/nexus/content/repositories/releases/org/hibernate/hibernate-core/3.6.0.Final/hibernate-core-3.6.0.Final.pom").openStream()));
        while ((s = r.readLine()) != null)
        {
            System.out.println(s);
        }
    }

}

And it prints the fetched pom file, so it's not that the JVM can't access the server because of SSL. It's something to do with the way Maven is accessing the JBOSS repo.

Come on, is no one else having this issue?

It has to be your network environment some how...

Is there a way you can hook to different internet service provider?

Just to nail down issue.

Never experience what you are going through ever

I'm sorry, but that's not it. I can access the URL just fine in a browser. It's a maven-ism. I have it working on a Linux box beside me. It has something to do with my OS X box + Maven. I'm working it out in a Maven IRC channel. Any further suggestions here are welcome too, but it's not a network provider issue.

Try the maven forum...

I found this for you http://blog.carlossanchez.eu/2011/01...aven-and-os-x/

Hope helps

I appreciate the help, but it's not a GPG error. And I'm already consulting with the Maven mavens (I'm typically considered a Maven guru, but even I get floored).

I can bypass the JBOSS repo issue on a Windows host, but on that host I get a different set of errors.

It appears the GWT libs aren't in the classpath. This is Roo?

**akutz** · Jan 31st, 2011, 06:51 PM

It was my own stupid fault. Look at the line I commented out from my .profile file:

Code:

# Java
# export JAVA_OPTS="-Xmx1024m -XX:MaxPermSize=1024m -Dsun.nio.ch.disableSystemWideOverlappingFileLockCheck=1 -Djavax.net.ssl.trustStore=$HOME/.keystore -Djavax.net.ssl.trustStorePassword=password"
export JAVA_OPTS="-Xmx1024m -XX:MaxPermSize=1024m -Dsun.nio.ch.disableSystemWideOverlappingFileLockCheck=1"
export MAVEN_OPTS="-DskipTests -Dbaselinetest.skip=true $JAVA_OPTS"
export ROO_HOME=$HOME/Servers/spring-roo/spring-roo-1.1.1.RELEASE

Everything now works on my OS X box. However, GWT compilation on my Windows system is still broken. Thoughts?

Try Roo Example Error

Tried with Maven 2.2.1

Got further by disabling SSL

SSL must be used

JBOSS cert in my keystore

Nope

Onto GWT not working

Fixed issue on OS X; GWT on Windows still fubar
