运行Eclipse：即使两者都是64位，也找不到Java

Question

I downloaded 64-bit Java from Oracle and 64-bit Eclipse and when I run eclipse it gives me error code 13 . I tried using the solutions from another user who asked this question but it didn't work. Any suggestions?

Answer 1

@Andreas hit the nail on the head with his suggested duplicate. The problem is that you are trying to run a 64-bit eclipse with a 32-bit java, or vice versa. Yes, I know you downloaded 64-bit eclipse and 64-bit java, but you didn't tell the 64-bit eclipse to use the 64-bit java. The eclipse.ini file is where you do that, and the -vm option is how.

In addition to the linked question, Eclipse provides a forum post on this subject at https://www.eclipse.org/forums/index.php/t/198527/ and a guide to using the eclipse.ini file at http://wiki.eclipse.org/Eclipse.ini .

The bottom line: you set the -vm option in the eclipse.ini file. The -vm must be on its own line, and the following line must only be the path to your javaw.exe. Both of those lines have to come before any -vmargs entry.

Once you get that done your 64-bit eclipse will run with the 64-bit java that you downloaded.

Answer 2

将vm选项和完整路径添加到javaw.exe
-vm C:\\Program Files\\Java\\jre6\\bin\\javaw.exe -startup
