title: Setting properties in Eclipse
body: <p>How can I manually add my own specific properties (user specific properties) to a project in Eclipse?</p>
  
  <p>Like when Android was developed, they added some user specific properties or same as like <code>ANTLR</code>. After these were developed, we use the properties in our project to create Android project etc..</p>
  
  <p>I am new to Eclipse and working on it. I have some plugins, I need to make a property in project that ask for some window where I can locate my file to choose and perform action like running those selected file.</p>
