IKVM jar to dll issues

Question

I'm having hard times trying to convert my .jar library in .dll and make it working by IKVM framework. I wrote a Java library that works fine since it has been tested succesfully in several java projects, but I strongly need the .dll for .NET.

When I launch the command:

ikvm -jar mylib.jar

everything is ok (I also tried with a Main file to be sure: it works).

But, when I type:

ikvmc -target:library mylib.jar

I got a lot of warnings but still it creates the .dll file. It is important to say that ALL the warnings are related to libraries that I DO NOT use in my project, but I am pretty sure are in the packages I imported in Maven that are essential to me. I don't know if the true problem is in this step since I read online to ignore those warnings, but to be sure I post a little bit of the output:

warning IKVMC0100: Class "junit.framework.TestCase" not found
warning IKVMC0100: Class "javax.servlet.http.HttpServlet" not found
warning IKVMC0100: Class "javax.servlet.ServletOutputStream" not found
warning IKVMC0100: Class "org.junit.Assert" not found
warning IKVMC0100: Class "junit.framework.TestSuite" not found
warning IKVMC0100: Class "org.apache.tools.ant.taskdefs.MatchingTask" not   found

Let us suppose this step is ok, now I have to import the IKVM libraries and the mylib.dll file in the References of my C# app. I did and the outcome is pretty strange: the autocomplete environment suggest me to use only 4 Java classes, ignoring the 99% of the others. I suppose that something went wrong, but it's pretty hard to me understand where and how to fix it.

Just more helpful info: I'm using Maven, Java8 (sdk 1.8) and IKVM 8. I also tried the same with IKVM 7 and still got the same errors. In the end, this is my pom.xml:

Answer 1

Just remove all code related to latest version of method and classes , and change it to lower version of library of java , may it work , because I have same error like this
