我正在按照openjfx.io 上的本指南来编译和运行HelloFX.java。

  • Ubuntu 18.04.2 LTS，通过适用于 Linux 的 Windows Sybsystem
  • 通过安装openjdkapt install openjdk-11-jre
  • 从此处下载 JavaFX ，从指南链接。
$ java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-post-Ubuntu-0ubuntu1.118.04)
OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Ubuntu-0ubuntu1.118.04, mixed mode, sharing)

这是我得到的：

$ export PATH_TO_FX=/home/connor/javafx-sdk-11.0.2/lib
$ javac --module-path $PATH_TO_FX --add-modules javafx.controls HelloFX.java
$ java HelloFX
Error: Could not find or load main class HelloFX
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

我认为这是我的 JFX 设置中的错误；XMing 设置中的错误会导致不同的错误。

（当前正在运行 Windows）我有一个名为GIGA
的 3TB USB 硬盘驱动器，我在其上创建了一个新的 3GB（当前未分配）分区。

我想将 ubuntu 安装到新分区，而不触及GIGA的其余部分。

我尝试在分区中创建一个新驱动器，我给了它字母U和标签UBUNTU，但 rufus 拒绝将它作为单独的驱动器读取，并坚持擦除整个GIGA。

有什么建议么？

我错过了fi某个地方。

我做到了。

[~/bin]: ./trashing_rm.sh
./trashing_rm.sh: line 70: syntax error: unexpected end of file
[~/bin]:

这是trashing_rm.sh：

#echo $@ #dbg

function help(){
    if [[ $2 = "--help:setup" ]]; then
        echo "`basename $0` --setup :"
        echo "appends to your bashrc (found at ~/.bashrc) the following line:"
        echo "\"alias rm='$0'\""
        echo "by executing this command:"
        echo "echo \"alias rm='$0'\" >> ~/.bashrc"
        exit 0 #don't print the other help.
    fi
    echo -e "\e[01m-- `basename $0` :: help --\e[00m"
    echo
    echo    "`basename $0` --help         : this help page"
    echo -e "`basename $0` <\e[04mfile\e[00m>         : trash \e[04mfile\e[00m to ~/TRASH.tar"
    echo    "`basename $0` -r | --recover : extract trash to ~/recovered-trash"
    echo    "`basename $0` --setup        : append some stuff to your .bashrc ( \"--help:setup\" )"
    echo "Return status:"
    echo "0 : No problems; file added to ~/TRASH.tar"
    echo "1 : File not found"
    echo "2 : minor problems - ~/TRASH.tar not found"
    echo "3 : printed help message"
    echo
    echo "* if this script is aliased to 'rm', do '/bin/rm' for the builtin remove util."
    echo
    echo "The source file is located at: $0"
    exit 0
}

if [[ $1 = "--help" ]]; then
    help
fi
###################################################

if [[ $1 = "--recover" ]]; then
    if [[ -e ~/TRASH.tar ]]; then
        #create recovered-trash if it doesn't exist.
        if [[ -d ~/recovered-trash ]]; then
            mkdir ~/recovered-trash
        cp ~/TRASH.tar recovered-trash
        tar -xf ~/recovered-trash/TRASH.tar
        rm ~/recovered-trash/TRASH.tar #remove the copy
        echo "trash file extracted to ~/recovered-trash"
    else
        echo "no trash file found :("
fi

if [[ ! $1 ]]; then #we aren't passed anything
    echo "What do you want to trash?  [do -? for help]"
    exit 0
fi


if [ ! -e $1 ]; then #file doesn't exist
    echo "$0 : error 1: file '$1' not found"
    exit 1
fi


if [ -e ~/TRASH.tar ]; then #if trash file already exists
    tar -r -f ~/TRASH.tar $1
    /bin/rm $1 #if this script is aliased to 'rm',
               #we call ourselves if we do 'rm'.
else
    tar -c -f TRASH.tar $1
    /bin/rm $1
fi

exit 0

（基本上，无论你传递什么它都会焦油，但我已经把它复杂化了。）

不确定这是否有帮助，但是：
