4. if maven is not deploying try executing this command

   Call mvn -Dbuild.version=Local -Doutput.dir="C:\\jboss-eap-7.0\\standalone\\deployments" clean install

5. try getting the entire project folder from others and check in your environment

6. if setting your environmental variables, then give SET PATH=C in command prompt as administrator

7. deleting the files unders .m2 folder /repository

   C:\\Users\\asophia.m2\\repository

8. also added the below mention paths in environment variables

    C:\\Oracle\\Middleware\\jdk160_18\\bin C:\\Program Files\\Java\\jre1.8.0_161 C:\\Program Files\\Java\\jdk1.8.0_161

Answer 1

You have to add the encryption jar in C:\\Program Files\\Java\\jdk1.8.0_161\\jre\\lib\\ext or whatever jdk you are using and then register it as well.

Since you are using Oracle jdk, you probably need their jar (JCE).

Quoting the documentation:

Installing Providers

In order to be used, a cryptographic provider must first be installed, then registered either statically or dynamically.

Static Registration

The configuration file is located in the following location:

Unix: /lib/security/java.security

Windows: \\lib\\security\\java.security

You can check the documentation for a well detailed explanation:
