Configuring Spring Roo for Java 7

When creating a Roo project with the “project” command, we have the option to specify the Java Version

$ roo
roo> project --topLevelPackage com.gordondickens.myproj --java 6 --projectName testapp

If we choose Java 7 with Roo 1.2.1, the code will not compile with AspectJ included.

Steps to change to Java 7:

• Change the Java version to 1.7
• Set the AspectJ version to 1.7.0.M1 or higher
• Set the Maven AspectJ Plugin to 1.4 or higher
• If using Hypersonic, change the version to 2.2.8 or higher
• Change the Hibernate version to 4.1.2 or higher
• (optional) Change the Hibernate Entity Manager to 4.1.2 or higher
