通过是修改eclipse.ini文件，在eclipse.ini文件上加上添加一行代码：
-vm 指定jdk11下bin的路径

如下代码
-startup
plugins/org.eclipse.equinox.launcher_1.5.800.v20200727-1323.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.1300.v20200819-0940
-product
org.eclipse.epp.package.jee.product
-showsplash
org.eclipse.epp.package.common
--launcher.defaultAction
openFile
--launcher.defaultAction
openFile
--launcher.appendVmargs

    -vm 
    C:/Program Files/java/jdk11.0.5/bin

-vmargs

-Dosgi.instance.area.default=@user.home/eclipse-workspace
