StatEt Eclipse 插件/RJ 的 ClassNotFoundException.Java9 的兼容性问题? [英] ClassNotFoundException for StatEt Eclipse plugin / RJ. Compatibility issue with Java9?

问题描述

我为 StatEt 安装了 RJ:

<代码>>install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-2.1")安装 Pakete nach 'C:/Users/eis/Documents/R/win-library/3.4'(da 'lib' nicht spezifiziert)versuche URL 'http://download.walware.de/rj-2.1/bin/windows/contrib/3.4/rj_2.1.0-13.zip'内容类型 'application/zip' 长度 342681 字节 (334 KB)已下载 334 KBversuche URL 'http://download.walware.de/rj-2.1/bin/windows/contrib/3.4/rj.gd_2.1.0-2.zip'内容类型 'application/zip' 长度 97222 字节 (94 KB)已下载 94 KBPaket 'rj' erfolgreich ausgepackt und MD5 Summen abgeglichenPaket 'rj.gd' erfolgreich ausgepackt und MD5 Summen abgeglichenDie heruntergeladenen Binärpakete sind inC:UserseisAppDataLocalTempRtmp0G5hW5downloaded_pa​​ckages

之后我对rj的包描述是:

我添加了文件夹

C:/Users/eis/Documents/R/win-library/3.4

到 StatEt Eclipse 首选项中的 R_LIBS:

当我尝试使用 RJ 启动控制台运行配置时出现以下错误:

Fehler: Hauptklasse de.walware.rj.server.RMIServerControl konnte nicht gefunden oder geladen werdenUrsache:java.lang.ClassNotFoundException:de.walware.rj.server.RMIServerControl

我用

• Windows 7
• Java JDK 9.01，
• 面向 JavaScript 和 Web 开发人员的 Eclipse，版本:Oxygen.2 Release (4.7.2)
• StatET 3.6.1

• R 版本 3.4.3

=> RJ for StatEt 是否与 Java9 兼容?

=> 如果是这样，我怎样才能正确安装 RJ for StatEt?

=> 如何/在哪里运行 R CMD javareconf 在 Windows 上?我在 r 的 bin 文件夹中尝试过，但参数 javareconf 未知.

相关问题和文章:

• 我的 R 环境配置没有太大变化

  I installed RJ for StatEt with:

  > install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-2.1")

  After that my package description of rj is:

  And I added the folder

  C:/Users/eis/Documents/R/win-library/3.4

  to R_LIBS in the StatEt Eclipse preferences:

  When I try to start my console run configuration using RJ I get following error:

  Fehler: Hauptklasse de.walware.rj.server.RMIServerControl konnte nicht gefunden oder geladen werden
  Ursache: java.lang.ClassNotFoundException: de.walware.rj.server.RMIServerControl

  • StatET 3.6.1

  • R version 3.4.3

  => Is RJ for StatEt compatible to Java9?

  => If so, how can I correctly install RJ for StatEt?

  => How/where do I run R CMD javareconf on windows? I tried in bin folder of r but the argument javareconf is not known.

  解决方案

  RJ 2.1 is not compatible to Java 9.0.1. You can point to different versions of JAVA if you have them installed. Please install Java 8 and select JRE 8 in your run configuration, for example:
