There is Java tool (it is called Mallet)
which i want to use in my .NET project.
To convert this tool to .NET library at first I've tried to build it in single .jar file using Apache Ant. I've done everything corresponding to instructions at link above.
Warning IKVMC0108: not a class file "cc/mallet/util/tests/TestPriorityQueue$1.cl
ass", including it as resource
(class format error "51.0")
The class format version 51 was introduced with Java 7.
IKVM most likely doesn't support that version yet and the file name you quote (
cc/mallet/util/tests/TestPriorityQueue$1.class) points at an anonymous inner class of
TestPriorityQueue that certainly is needed for the library to work correctly.
My suggestion: compile Mallet using an older JDK or at least using the
-target switches set to
6 (to ensure that it's compile for Java 6).
