git clone 후 minedojo/sim/malmo/Minecraft/build.gradle 수정
수정후 의존성 다시 업데이트. 다만 아직 문법이해가 안돼서 어려운점있음

1. 먼저 modifedminedojo의 root directory 다운로드 받기
2. build.gradle 수정 맨처음 나오는 repositories와 60줄즈음의 classpath수정
3. minedojo/sim/malmo/Minecraft/에서 gradle 실행 권한 준 다음 chmod +X gradle 다음의 명령어 수행
   sudo ./gradlew clean build --refresh-dependencies

Gradle clean error, execute by sudo

Still if you get error maven path error maven package

> Could not find MixinGradle-dcfaf61:MixinGradle:dcfaf61.
Before using url path

maven {
    url 'file:///home/ubuntu/MineDojo/MixinGradle-dcfaf61/MixinGradle/dcfaf61'
}

Solution after remove as is path, and change it to flat Dir

:mixingradle:0.6-SNAPSHOT'){ // 0.#

        flatDir {
            dirs '/home/ubuntu/MineDojo/MixinGradle-dcfaf61/MixinGradle/dcfaf61'
        }

근데 그래도 다음문제 생김. 권한에러
raise child_exception_type(errno_num, err_msg, err_filename) PermissionError: [Errno 13] Permission denied: '/tmp/tmp6zkikl_p/Minecraft/launchClient.sh'

### Change apt package name from vnc4server to tigervnc-standalone-server

solution-> change package name
`sudo apt install tigervnc-standalone-server -y`
