使用 IKVM 的 MissingMethodException
MissingMethodException using IKVM
我正在尝试在 C# 中使用 Stanford CoreNLP（这是一个 Java 项目）。
我发现这个 Nuget package 包含使用 IKVM 转换为 .NET 的 CoreNLP，它工作正常，但是我还需要对 java 项目做一些修改。
我从 google 中找到的 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 下载了 CoreNLP，我正在这样做：
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只是一些关于无法找到的引用分类的警告：

P.S.: 我也试过转换 protobuf.jar，但没有帮助解决下面描述的问题。
问题是：当我为新编译的引用（6 个 dll）替换 Nuget 引用时，它编译正常（找到所有引用），但抛出此 MissingMethodException：附加信息：找不到方法: 'Void edu.stanford.nlp.pipeline.StanfordCoreNLP..ctor(java.util.Properties)'.
任何人都可以阐明一下吗？
我想我明白了。这是修复的内容：
- 删除了 Nuget 包 IKVM 8.0.5449.1
- 已安装 Nuget 包 IKVM 8.0.5449.0（这是我用来转换 JAR 文件的 version）
- 清理并重建。
如果我理解正确，我用来转换 JAR 文件的 ikvmc.exe 必须与引用的运行时 DLL 的版本相同。
