Solve the Problem of j2ecolcould not find Jar tool executable

 

In eclipse, an error occurred while using proguard to generate the create obfuscated package:

 

 

Cocould not find Jar tool executable. The jar tool requires a full JDK installation. Specify a full JDK installation int the preferences.

Reason cocould not find Jar tool executeable

It means that a complete JDK installation is required.

Solution:

 

In "window -- preferences -- Java -- installed JRE, 'windows-preferences-Java-installed jres': Change the installed JRE directory to the JDK installation directory.

 

Cause:

 

 

During the obfuscation process, the jar files generated by the obfuscation tool must be pre-verified again.

In this case, the preprocessing tool looks for and calls the executable files of the jar tool from the environment variables.

Eclipseme is generally searched under the JRE installation directory.

If this problem occurs, it must be because eclipseme found at least one JDK in the installed JRE (Java subclass. In this case, eclipse recognizes JRE rather than JDK by default.
