I want to taste the latest jdk10, Since Java removed the generation of JRE directory in JDK folder when it was installed from java9, and gradle was not compatible with JDK installation mode without JRE folder, it had to switch back to java8, so after repeatedly unloading and reinstalling JDK, an error occurred when starting eclipse Error:opening registry key ‘Software/JavaSoft/JRE’

The error information is as follows:

Obviously, the system does not find the JRE, and the current java version is still not displayed in the CMD – & gt; Java – version. Of course, the environment variable Java_ Home and path are checked correctly. It is suspected that Java is not found correctly due to cache or registry_ Then, with the mentality of having a try, compare the previous environment variable name with the “Java” in the path_ The key value of “home” is replaced by the uppercase “Java”_ “Home” has been changed to lowercase “Java”_ Then CMD – & gt; Java – version can display the information of jdk8 normally, restart eclipse, perfect solution! Share here, hope to help you!
