Remove gradle nature from eclipse project
<p>I just mirrored a repo that uses maven, however when manually editing the maven modules' .project and .classpath files I accidentally used gradle instead of maven. I've since changed the files manually to maven and have gotten rid of all gradle related text I could find, however eclipse is giving me this error on all modules</p>

<blockquote>
  <p>Missing Gradle project configuration file:
  .settings/org.eclipse.buildship.core.prefs    EssentialsX     Unknown Gradle
  Project Configuration Marker</p>
</blockquote>

<p>How can I solve this error?</p>

<p>Also, here is this specific maven module's <code>.project</code> file</p>

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;projectDescription&gt;
    &lt;name&gt;Essentials&lt;/name&gt;
    &lt;comment&gt;&lt;/comment&gt;
    &lt;projects&gt;
    &lt;/projects&gt;
    &lt;buildSpec&gt;
        &lt;buildCommand&gt;
            &lt;name&gt;org.eclipse.jdt.core.javabuilder&lt;/name&gt;
            &lt;arguments&gt;
            &lt;/arguments&gt;
        &lt;/buildCommand&gt;
        &lt;buildCommand&gt;
            &lt;name&gt;org.eclipse.m2e.core.maven2Builder&lt;/name&gt;
            &lt;arguments&gt;
            &lt;/arguments&gt;
        &lt;/buildCommand&gt;
    &lt;/buildSpec&gt;
    &lt;natures&gt;
        &lt;nature&gt;org.eclipse.m2e.core.maven2Nature&lt;/nature&gt;
        &lt;nature&gt;org.eclipse.jdt.core.javanature&lt;/nature&gt;
    &lt;/natures&gt;
&lt;/projectDescription&gt;
</code></pre>

<p>And here is the <code>.classpath</code> file</p>



<pre><code>&lt;classpath&gt;
    &lt;classpathentry kind="src" path="src"/&gt;
    &lt;classpathentry kind="src" path="test"/&gt;
    &lt;classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/&gt;
    &lt;classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"&gt;
        &lt;attributes&gt;
            &lt;attribute name="maven.pomderived" value="true"/&gt;
        &lt;/attributes&gt;
    &lt;/classpathentry&gt;
    &lt;classpathentry kind="output" path="bin"/&gt;
&lt;/classpath&gt;
</code></pre>

<p>Thank you for your time!</p>
