问题

在IntelliJ中将我的JavaFX应用程序构建为JavaFX应用程序,并在控制台中使用以下命令运行jar文件时:

java -jar RaspberryShell.jar

我收到了这个错误:

错误:找不到或加载主类de.Jan.Raspberry.Shell.Main
原因:java.lang.NoClassDefFoundError: javafx/application/Application

我还在artifact中设置了主类,这不应该是个问题,如果我直接在IntelliJ中运行它,代码可以正常运行。

有人有想法吗?

英文:

When I try to build my javafx application in intellij as a JavaFX Application and I run the jar in console with

> java -jar RaspberryShell.jar

I get this error:

Error: Could not find or load main class de.Jan.Raspberry.Shell.Main
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

I also set the main class in the artifact that shouldn't be a problem and the code runs fine if I run it direct in intellij.

Does anyone have ideas?

尝试将以下内容添加到路径中:

--module-path /usr/local/javafx-sdk-14.0.1/lib --add-modules javafx.controls,javafx.fxml

只需将 /usr/local/javafx-sdk-14.0.1/lib 更改为包含 JavaFX 的目录即可。lib 目录应包含一些 .jar 文件,包括 javafx.fxml.jar。

英文:

Try to add this to the path:

--module-path /usr/local/javafx-sdk-14.0.1/lib --add-modules javafx.controls,javafx.fxml

Just change /usr/local/javafx-sdk-14.0.1/lib to the directory which contain javafx. The lib directory should contain some .jar files, including javafx.fxml.jar

你的运行时Java不包含JavaFX。更换为一个包含JavaFX的版本。

Your runtime Java does not include JavaFX. Change to one who does.

当您运行它时,请单击下拉箭头 -> 运行配置 -> 参数,然后将以下内容粘贴到VM参数中:(用您自己的lib路径替换)
--module-path "C:\Program Files\FX\javafx-sdk-11.0.2\lib" --add-modules javafx.controls,javafx.fxml
点击应用并运行!

英文:

When you run it, click on the drop down arrow -> Run configurations -> Arguments
Then paste the following into VM arguments: (Replace with your own path for lib)
--module-path "C:\Program Files\FX\javafx-sdk-11.0.2\lib" --add-modules javafx.controls,javafx.fxml
Press apply and run!

这个错误是因为你的机器上可能安装了两个JDK,一个是较旧版本的,比如包含javafx/application/Application作为JDK的一部分的Java 8,另一个是较新版本的,不包含该部分。
解决方法:
卸载新的JDK版本,保持JDK 8。

英文:

This Error is because you may have two JDK installed on your machine an older version like Java 8 which contains a javafx/application/Application as part of the JDK and a higher which does not.
Solution:
Uninstall new JDK version and maintain JDK 8
