Cocould not find Jar tool executable title Solution

In eclipse, an error occurs when proguard is used to generate an obfuscated package:

Cocould not find Jar tool executable.

The jar tool requires a full JDK Installation

Specify a full JDK installation int the Java Preferences.

Reason cocould not find Jar tool executeable

A complete JDK installation is required, but I have installed a positive JDK ..

Solution:

In "window -- preferences -- Java -- installed JRE, the corresponding English version is "Windows-preferences-Java-installed jres". Correct the installed JRE directory to the JDK installation directory ..

Cause:

In the hybrid process, the jar files generated by the hybrid tool need to be pre-verified again. In this case, the preprocessing tool looks for and calls the executable file of the jar tool from the environment variable. Eclipseme is usually searched under the JRE installation directory. If this title is generated, it is determined that eclipseme has found at least one JDK in the installed JRE (Java subclass. In this case, in windows, eclipse will be familiar with JRE instead of JDK.
