Renjin NullPointerException異常

Question

如果我在 Maven 中運行具有以下依賴項的 Renjin，我會在 Java 中得到 NullPointerException：

 <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>

我在 Java 中得到的異常是：

我已經在 R 版本 4.0.2 中測試了我的代碼，它確實有效！

請你能幫幫我嗎？

感謝您的支持！

最好的祝福，

Answer 1

使用最新版本的 Renjin（版本 0.9.276）和 Maven 依賴項：

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

我在 Java 中得到以下異常：

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

所以我的問題是：Renjin 的新版本什么時候出來？

感謝您的支持！

最好的祝福，
