Error analysis:
0

first of all, through the error report, it seems that the JVM is 32bit, which does not meet the requirements of 64bit program

View Directory: C:// programdata/Oracle/Java/javapath\

Here are three shortcuts: java.exe, javaw.exe, javaws.exe. Check the shortcuts of three programs with the same name under JRE/bin with the attribute of JDK1.8 32bit

Solution:

Install 32 bit JRE in the machine, create a shortcut for the three programs with the same name under JRE/bin/and copy the shortcut to C:// program data/Oracle/Java/javapath to replace the original one

Restart eclipse, success
