Why I get artifact 'saxon:saxon:6.5.3@jar' not found

I try to compile Spring security examples and when I run the gradlew.bat eclipse command (under windows 7) I get the following error

Failed to notify build listener. > Failed to notify build listener.

Could not resolve all dependencies for configuration ‘:runtime’.

Artifact ‘saxon:saxon:6.5.3@jar’ not found. anybody ?

Well I found the problem

I removed all dependecies run the gradlew.bat eclipse It moved to some other error but later in the build process retuned the depenedcies now I get all the green messages

That’s a question for the Spring Security developers. Seems like they (or some plugin) want you to set ‘appEngineSdkRoot’ in ‘gradle.properties’.
