<p>The dependencies in build.gradle of two modules as show below.</p>

<pre><code>dependencies {
    compile 'org.jsoup:jsoup:1.8.2'
}
</code></pre>

<p>And this is build.gradle of app.</p>

<pre><code>dependencies {
    compile project(':moduleA')
    compile project(':moduleB')
}
</code></pre>

<p>How to fix it?? Thanks.</p>

<hr>

<p>This is my whole build.gradle of app</p>
