NppExec无法编译Java

Question

我试图让NPPexec编译我的java程序，但是插件不起作用。我试图将它定向到当前的文件，我放弃了它的工作能力，只让它转到我的代码文件夹，仍然保持正常。Javac似乎工作得很好，除了它没有针对当前文件。最后，每当它试图使用java命令运行程序时，它就会抓狂，表现得好像没有注册表项或其他任何东西一样。我的java工作是在普通命令提示符下找到的，所以我不知道该做什么。

输入：

 cd desktop
    cd code
    javac $(FILE_NAME.JAVA)
    java $(NAME)

输出：

 CD: desktop
    Current directory: C:\Program Files (x86)\Notepad++
    CD: code
    Current directory: C:\Program Files (x86)\Notepad++

Answer 1

对于nppexec命令，请尝试如下：

cd "$(CURRENT_DIRECTORY)"
javac $(FILE_NAME)
java $(NAME_PART)

它每次都适用于我(前提是指向路径变量可执行文件的路径已经正确地添加到了中)。

但是，不确定您所得到的错误，但是如果上面的错误不能工作，这可能会有所帮助。
