Java Runnable.jar在Ubuntu上工作，但在Windows上不工作

在Windows上，从cmd运行.jar时按下submit按钮的方式如下：

MemoryClassLoader

中的第15行：

private final MemoryFileManager manager = new MemoryFileManager(this.compiler);

this(Collections.singletonMap(classname, filecontent));

以及

MemoryFileManager

中的第15行：

super(compiler.getStandardFileManager(null, null, null));  

看到程序在Eclipse和Ubuntu上正确运行，我猜它与javax.tools导入的路径有关？在项目中的某个时刻，我记得我让eclipse从使用JRE转向使用JDK，因为这些类都有错误。我需要做什么才能使它在Windows上运行？我很抱歉，如果这是一个愚蠢的问题，如果它是显而易见的：p

谢谢大家!

编译器

在

MemoryClassLoader.（MemoryClassLoader.java:12）

中为空。 如果没有任何编译器，则返回null

看起来您确实需要安装JDK来运行这个（或者至少是类路径上的tools.jar）：

请将命令行输出复制/粘贴为文本，而不是获取其屏幕截图。文本大小适合阅读，可搜索。完成，对此表示抱歉谢谢！我很确定我已经安装了JDK，因为我用它在Eclipse中运行程序。如果我想继续使用JavaCompiler，除了安装它之外，我还需要做什么吗？只要您在类路径上安装了它，它就会正常运行。如果您安装了多个版本的Java，那么JRE在路径上可能是一个问题。Eclipse也有自己的编译器，它也可以返回。
