java - Renjin 无法加载包

Question

我是 Renjin 的新手。我正在尝试在 Java 应用程序中使用 Renjin。我正在尝试开发显示 here 的示例.

我正在使用 gradle 进行编译，正如 renjin 的 web page 中所推荐的那样.

因此，当我运行 gradle build 时，使用 gradle build 一切正常。

Building with Renjin 0.8.2527
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar UP-TO-DATE
:startScripts UP-TO-DATE
:distTar UP-TO-DATE
:distZip UP-TO-DATE
:assemble UP-TO-DATE
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build UP-TO-DATE

BUILD SUCCESSFUL

Total time: 1.954 secs

但是，当我想使用 gradle run 运行应用程序时，我得到了这个。

FAILURE: Build failed with an exception.

我试过不同的包，结果相同。我在网站 http://packages.renjin.org/ 中搜索了包裹并且包存在，所以我认为这与可用性无关。

有人遇到过同样的问题吗？并解决了？

提前致谢。

您需要将 a4base 包添加到您的项目中。

使用 gradle，您可以添加以下行:

dependencies {
    compile "org.renjin.bioconductor:a4Base:1.27.0-b3"
}

Gradle 将下载 JAR 并将其提供给您的应用程序。

您可以在此处阅读有关将 R 包与 Java 应用程序结合使用的更多信息:
