Hello,
My maven setup worked fine and then I moved to an artifactory
repository (because db4o is not available in maven yet).
Suddenly I had problems compiling my app (error below)
[ERROR] BUILD FAILURE
[INFO]
------------------------------------------------------------------------
[INFO] Compilation failure
/Users/pclaassen/Documents/workspace/tmp/src/main/java/com/musmato/dao/
BaseFactory.java:[50,43] type parameters of <T>T cannot be determined;
no unique maximal instance exists for type variable T with upper
bounds T,java.lang.Object
/Users/pclaassen/Documents/workspace/tmp/src/main/java/com/musmato/dao/
BaseFactory.java:[50,43] type parameters of <T>T cannot be determined;
no unique maximal instance exists for type variable T with upper
bounds T,java.lang.Object
This looks like a java generics issue but:
zorgon:tmp pclaassen$ java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)
So I am on the latest version of java.
Here is my slightly sanitized pom.xml.
Does anybody have some advice?
