imvmc.exe errors when compiling a basic jar file

I am having problems getting ikvmc.exe to compile a rudimentary jar file. Here is the command line and result.

.\IKVMc.exe .\hello.jar                                                                                                       pwsh  09:57:23 

I created the jar file from a basic hello world.

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

Jar creation build against openjdk 11.0.12

javac hello.java
jar hello.jar helloworld.class

I am pretty much ignorant of java development in general so potentially I am missing something basic. I do know .NET pretty well and fostered a library that used IKVM for exposing a java library on dotnet. I am attempting to get this working on dotnet core but the ikvmc.exe step fails with a similar error so I tried this basic example to debug.

This seems like an odd version to be using: 8.2.0-prerelease.392.

8.2.0 was released almost two weeks ago.

Also, ikvmc will require that all required dependent DLL files are specified using -reference. That includes IKVM.Java from the bin package. And it requires -runtime be specified to to point to IKVM.Runtime.

This is all much easier using IKVM.Maven.Sdk or IkvmReference in your build files, however.

Hey @wasabii I am trying out IKVM to convert jar to dll. I started with ikvm-7.2 and later came across the latest version ikvm-8.7.0.

I am trying to convert from the command line. Command -> ikvmc -target:library -out:offlinepos.dll -r:offlinepos.jar Error ->

The jar is compiled with java 8. Also, is there any alternative way to convert using Visual Studio.

-r is for adding a reference to an assembly. I believe the input files have no argname.

Yes, there is copious documentation on using IkvmReference on the Readme

Hey Did you get the solution for the issue you were facing

varratna avatar Jan 09 '24 14:01 varratna

@varratna

-r is for referencing the dependent .NET assemblies.

You've used it to reference a JAR file. So it is breaking saying it isn't a PE image with metadata (a .NET assembly).

We strongly recommend using IkvmReference or MavenReference.

As I said, you should favor using IkvmReference or MavenReference.

Else, you will need to add a -r argument for every assembly that forms the reference assembly pack for runtime you are intending to target. For .NET Framework this will be all of the reference assemblies installed by the various targeting packs.

For Core, this will be all of the assemblies for the Microsoft.NETCore.App.Ref pack of the specific version of .NET Core you want to target.

wasabii avatar Jan 09 '24 16:01 wasabii

Hi Jerome Haltom,

Thanks for your reply .

I shall try using IkvmReference or MavenReference.

I just tried using the -r argument and execute the below command , but still it was giving me the same error.

I was expecting an error but it should have referred to some other assembly from the Microsoft.NETCore.App\6.0.25 folder instead of System.Runtime.dll

Am I doing something wrong , can you verify the below command.

Command - ikvmc -reference:"C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.25\System.Runtime.dll" -out:hha-pricer-application-1.12.0.dll hha-pricer-application-1.12.0.jar

Hi

I am able to convert the java.jar file to .dll file I am trying to access the main class and create and object to call the respective methods

but I am not able to get the namespace of the main class in the .dll

It did not give any error or warning . I used the IKVM reference method.

eg hha-pricer-application-1.12.0.jar\gov\cms\fiss\pricers\hha - my main class in java.jar - this namespace and class not accessible in .net (.dll) other folder structure hha-pricer-application-1.12.0.jar\com - these namespace and classes are accessible hha-pricer-application-1.12.0.jar\nonapi\io\github\classgraph - these namespace and classes are accessible

Exe net6.0 enable enable

can you help me out in this

Thanks, varratna
