IKVM - Java Virtual Machine for .NET

Nuget GitHub

IKVM.NET is an implementation of Java for the Microsoft .NET Framework and .NET Core.

IKVM.NET includes the following components:

  • A Java virtual machine (JVM) implemented in .NET
  • A .NET implementation of the Java class libraries
  • A tool that translates Java bytecode (JAR files) to .NET IL (DLLs or EXE files).
  • Tools that enable Java and .NET interoperability
  • With IKVM.NET you can run compiled Java code (bytecode) directly on Microsoft .NET Framework or .NET Core. The bytecode is converted on the fly to CIL and executed.

Documentation

See the tutorial to get started or IKVM.NET In Details for a more in-depth look.

Support

  • .NET Framework 4.6.1 and higher
  • .NET Core 3.1 and higher
  • .NET 5 and higher
  • Java SE 8

Build

Project should open within Visual Studio. Project can also be built with MSBuild on a Windows host. Project cannot currently be built on a Linux host, nor with an exclusively .NET Core version of MSBuild.

The OpenJDK JDK8u source hierarchy and build results for Linux/x64 is required. These build artifacts cannot be built on Windows, or modern Linux hosts. Instead, they must be built on a host with GCC 4.3 available. Debian Lenny is known to work acceptably. The CI/CD GitHub action can serve as a demonstration of this.

The GitHub action's generated artifact can simply be extract into the appropriate spot in openjdk8/build to avoid building it yourself. Navigate to the GitHub Actions, find the latest successfuly build for the branch you're concerned with, and download the openjdk8-build-linux-x86_64-normal-server-release artifact. Extract this zip file into openjdk8/build.

IKVM includes a native library named 'ikvm-native' which must be built for the JNI functionality to work. The solution includes .vcxproj files that build both the win-x86, win-x64, linux-x86 and linux-x64 versions of these libraries. However, the linux-* version require WSL to be enabled on your development machine. Within this WSL distribution ensure you have installed the GCC toolset. For Debian based distributions, this should be as simple as typing apt-get install g++.

Project

  • IKVM.sln Main solution file for the project.
  • IKVM.artifacts.msbuildproj MSBuild project file that builds the output artifacts, including the NuGet packages.
  • IKVM.Runtime The main executable core of IKVM. Provides services used by IKVM.Java.
  • IKVM.Java The OpenJDK distribution included with IKVM. This project is heavily customized to compile the OpenJDK Java source files and produce a .NET assembly from them.
  • ikvm java compatibility executable. Launches a JVM. Can be used to execute Java applications with entry points.
  • ikvmc ikvmc executable. Transforms Java class files or JAR files into .NET libraries or executables.
  • ikvmstub ikvmstub executable. Generates Java JAR files for .NET assemblies. When building Java code that depends on .NET code, these stubs can be used as references.
  • IKVM.Tests Various unit tests against IKVM functionality.
  • IKVM.Runtime-ref "Reference" version of the IKVM.Runtime project. Due to a circular dependency between IKVM.Java and IKVM.Runtime, IKVM.Java must build against a partial copy of IKVM.Runtime.
  • IKVM.Java-ref "Reference" version of the IKVM.Java project. Due to the circular dependency between IKVM.Java and IKVM.Runtime, IKVM.Runtime must build against a partial copy of IKVM.Java.
  • IKVM-pkg To untangle the ProjectReferences between the circular dependencies, this project generates the NuGet package output, including all of it's required dependencies, and the full version of the underlying IKVM assemblies.

Versioning

IKVM uses the Semantic Versioning specification, with a unique twist. Since the project tracks compatibility with the Java SE specification, the major version is always the version of the JDK we claim to support. Otherwise major/breaking IKVM releases are denoted by an increment of the minor version. Other releases are denoted by an increment of the patch version.

Semantic Versioning is accomplished automatically by GitVersion in Mainline mode. The main branch functions as the release branch. Every commit to main results in an increment of the patch version and a release. The develop branch represents a prerelease staging area. Builds within the develop branch inherit the NEXT version number of the main branch, with a prerelease tag followed by the number of commit separating develop from the last release.

Increases in the major and minor version are accomplished manually by introducing a commit with a message containing a line such as +semver: major or +semver: minor. The process of creating a new major or minor release is simply to bump the version with the introduction of a commit message. The GitHub Actions should automatically generate the git tag and GitHub release, and publish the proper NuGet packages to the proper places.

TikaOnDotNet

Bare-bones IKVM Java-to-.NET port of Apache Tika. You'll want to install TikaOnDotNet.TextExtractor.

Stanford.NLP.CoreNLP

Stanford CoreNLP provides a set of natural language analysis tools which can take raw English language text input and give the base forms of words, their parts of speech, whether they are names of companies, people, etc., normalize dates, times, and numeric quantities, and mark up the structure of sentences in terms of phrases and word dependencies, and indicate which noun phrases refer to the same entities. Stanford CoreNLP is an integrated framework, which make it very easy to apply a bunch of language analysis tools to a piece of text. Starting from plain text, you can run all the tools on it with just two lines of code. Its analyses provide the foundational building blocks for higher-level and domain-specific text understanding applications.

IKVM.Maven.Sdk

Java SE 8 Virtual Machine for .NET (Maven SDK)

CuratorIkvm

Curator client library & recipes for Zookeeper. This is the IKVM version; which is to say that this is compiled from Java to .NET

OpenNLP.NET

The Apache OpenNLP library is a machine learning based toolkit for the processing of natural language text. It supports the most common NLP tasks, such as tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing, and coreference resolution. These tasks are usually required to build more advanced text processing services. OpenNLP also included maximum entropy and perceptron based machine learning.
