Can't compile new version 1.3.170 from scratch

[Manfred Rosenboom]

Hi Thomas,

I have just downloaded the current version and have tried (as always) to compile the new version in my H2 Eclipse project. Works usually without any problem. But with the new 1.3.170 version I get the following compile errors:

Make sure you are using an appropiate compiler (1.6 or above) the messages seem to be related to the fact that in 1.5 there is no override annotation allowed for method overriden in interfaces.

Hi Christoph,

Many thanks for your hint! I had already used a Java SE 6 SDK, but I had used 1.5 compliant compiling in Eclipse.for the older H2 versions to make them compilable by default.Now everthing works okay :-)

Best,
Manfred

Hi,

This is quite a common problem, I wonder if there is a way to let Eclipse give a "nice" error message (special source code with a warning or so).

Regards,

Thomas
