使用 netbeans 8.1 的 Java Web 应用程序

I'm using netbeans 8.1 and me and my team going to build a web application project with github. The problem is when the clone from github WEB-INF and Source packages are not coming. This is my gitignore file

# NetBeans project files
nbproject/private/
build/
build.xml
nb-configuration.xml

# IDE files
.idea/

# Compiled Java classes
*.class

# Compiled JSP files
*.jsp.class

# Logs and databases
*.log
*.sqlite
*.sqlite3
*.sql

# Package files
*.jar
*.war
*.ear

# Mac OS specific files
.DS_Store

# GlassFish server specific files and directories
glassfish-resources.xml
build.properties
build-impl.xml
dist/

I want fix the problem what should i add to gitignore or how to clone and run the project correctly
