Renjin NullPointerException

问题描述

如果我在Maven中运行具有以下依赖项的Renjin，则会在Java中获得NullPointerException：


node-gyp rebuild

我在Java中遇到的异常是：

 <dependencyManagement>
<dependencies>
  <dependency>
    <groupId>org.renjin</groupId>
    <artifactId>renjin-script-engine</artifactId>
    <version>0.9.2725</version>
  </dependency>
  <dependency>
    <groupId>org.renjin.cran</groupId>
    <artifactId>e1071</artifactId>
    <version>1.7-0-b8</version>
  </dependency>
  <dependency>
    <groupId>org.renjin.cran</groupId>
    <artifactId>ranger</artifactId>
    <version>0.11.2-b1</version>
  </dependency>
</dependencies>

我已经在R版本4.0.2中测试了我的代码，它确实有效！

请帮助我。

感谢支持！

解决方法

使用具有Maven依赖项的最新版本的Renjin（版本0.9.276）：

<groupId>org.renjin</groupId>
<artifactId>renjin-script-engine</artifactId>
<version>3.5-beta76</version>

我在Java中得到以下异常：

org.renjin.eval.EvalException: cannot read workspace version 3 written by R 3.5.0; need R 3.5.0 or newer

所以我的问题是：人人的新版本何时发布？

感谢支持！
