Spring Roo RC1 unsupported class version issue

[mschipperheyn]

Prob to do with the fact that I use JDK 1.5.09 but I thought I would mention it here.

I got this going through the blog post with the hello world for Roo

Cheers,

Marc

When does this happen? It looks like you're trying to load up a Roo-created project and you're experiencing a version issue. If the Roo shell works, it indicates you have Java 5 or above. Please take a look in the pom.xml at the Java version defined against the compiler. You might also be interested in looking at how Roo handles Java version numbers, which is detailed at:

http://jira.springsource.org/browse/ROO-68

Just thinking aloud here, I am wondering if you possibly created this project with an early version of Roo, have the pom.xml indicating a Java version you do not have, have %JAVA_HOME% pointing at an unexpected JDK version, or maybe even have a corrupted JAR in your %HOME%/.m2/repository directory.

If you continue to have difficulties with this, would you please try:

mkdir \clinic
cd \clinic
roo
props <----- record the output of this command in a Jira ticket
script clinic.roo
quit

Then mvn -X tomcat:run <--------- please also include this output in Jira

This will produce a lot of debug output, including details of the Java version. Would you please post this output (along with the created pom.xml) to a Jira ticket and we'll be pleased to assist you get started with Roo. We look forward to being of help...

I reproduced the same error when handling with .roo samples.
I used jdk 1.5 and after installing jdk 1.6 and setting JDK_HOME and JAVA_HOME and Path to the new version all worked ok.
