使用IKVM的MissingMethodException [英] MissingMethodException using IKVM

问题描述

我正在尝试在C#中使用Stanford CoreNLP(这是一个Java项目).

I'm trying to use Stanford CoreNLP (which is a Java project) in C#.

我发现了这个 Nuget软件包，其中包含转换为CoreNLP的.NET使用IKVM，并且运行良好，但是我也需要在Java项目上进行一些修改.

I found this Nuget package which contains CoreNLP converted to .NET using IKVM, and it's working fine, however I need to do some modifications on the java project as well.

我从 Github 下载了CoreNLP，我可以从Ant构建CoreNLP JAR，并且运行良好在eclipse中，但是在将JAR转换为DLL时遇到问题.根据一些构建日志，我在Google中找到了，我正在这样做:

I downloaded CoreNLP from Github, I can build the CoreNLP JAR from Ant, and it's also running fine in eclipse, however I'm having problems in converting JAR to DLL. Based on some build-log that I found in google, I'm doing this:

ikvmc.exe  -version:2.1 ..\lib\joda-time.jar -out:joda-time.dll 
ikvmc.exe  -r:joda-time.dll -version:0.4.7 ..\lib\jollyday-0.4.7.jar -out:jollyday.dll 
ikvmc.exe  -version:0.23 ..\lib\ejml-0.23.jar -out:ejml-0.23.dll 
ikvmc.exe  -version:1.2.10 ..\lib\xom-1.2.10.jar -out:xom.dll 
ikvmc.exe  -version:1.0 ..\lib\javax.json.jar -out:javax.json.dll 
ikvmc.exe  -r:joda-time.dll -r:jollyday.dll -r:ejml-0.23.dll -r:xom.dll -r:javax.json.dll -version:3.5.0 ..\javanlp-core.jar -out:javanlp-core.dll 

我从以下转换中得到的都是关于找不到的有关引用分类的一些警告:

All I get from the following conversions are a few warnings about referenced classed that can't be found:

P.S .:我也尝试过转换protobuf.jar，但对下面描述的问题没有帮助.

P.S.: I also tried converting protobuf.jar, but didn't help with the problem described below.

问题是:当我将Nuget引用替换为新编译的引用(6个dll)时，它可以正常编译(查找所有引用)，但是抛出此 MissingMethodException:其他信息:未找到方法:'Void edu .stanford.nlp.pipeline.StanfordCoreNLP..ctor(java.util.Properties)'.

Problem is: when I replace the Nuget references for my freshly-compiled references (6 dlls), it compiles fine (finds all references), but throws this MissingMethodException: Additional information: Method not found: 'Void edu.stanford.nlp.pipeline.StanfordCoreNLP..ctor(java.util.Properties)'.

谁能阐明一些想法?

推荐答案

我想我已经知道了.这是固定的内容:

I guess I figured it out. Here is what fixed:

1. 删除了Nuget软件包IKVM 8.0.5449.1
2. 已安装Nuget软件包IKVM 8.0.5449.0(即版本我当时用来转换JAR文件)
3. 清洁并重建.

1. Removed Nuget Package IKVM 8.0.5449.1
2. Installed Nuget Package IKVM 8.0.5449.0 (which was the version I was using for converting my JAR files)
3. Clean and rebuild.

如果我正确理解，我用来转换JAR文件的ikvmc.exe必须与所引用的运行时DLL的版本相同.

If I understand correctly, the ikvmc.exe I used to convert my JAR files must be the same version of the referenced runtime DLLs.
