在CentOS7上安装KETTLE8的时候用到的，解决了以下问题
org.eclipse.swt.SWTError: No more handles [MOZILLA_FIVE_HOME=''] (java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-mozilla-gtk-4335 in java.library.path
no swt-mozilla-gtk in java.library.path
/root/.swt/lib/linux/x86_64/libswt-mozilla-gtk-4335.so: libxpcom.so: cannot open shared object file: No such file or directory
Can't load library: /root/.swt/lib/linux/x86_64/libswt-mozilla-gtk.so
下载后上传到linux运行以下命令
# tar -xvf xulrunner*.tar
# cd ./xulrunner
# ./xulrunner -register-global
