Could not find or load main class in STS/Eclipse
<p>I have a main method in a package in one of my projects. Say, the package is <code>com.ant.car</code>. I am trying to run and/or debug this main method, and I keep getting the error <code>Could not find or load main class com.ant.car</code>.</p>

<p>I've searched this problem, and it seems like I can't figure out what is wrong.</p>

<p>1) I've checked run configurations. In Run->Run Configurations, I've checked that the Main class is com.ant.car.</p>

<p>2) I've checked build path. If I right click on the project, I select Build->Build Path, and under the Libraries tab I make sure there are no missing folders with red Xs next to them.</p>

<p>Not really sure what else to do. Any suggestions?</p>
