title: BUG! exception in phase 'semantic analysis'
body: <p>I have a 1.1.7 spring-boot app using Gradle 1.10 &amp; jdk1.8.  I use Groovy/Spock for testing It has two dependencies - jars build with Apache Maven 3.1.1 and jdk 1.8.  I build the jars and them copy them into the /lib directory.  Then I try and build with "gradle clean build.</p>
  
  <p>Here is part of my gradle file:</p>
  
  <pre><code>apply plugin: 'java'
  apply plugin: 'groovy'
  apply plugin: 'idea'
  apply plugin: 'spring-boot'
  apply plugin: 'jacoco'
  apply plugin: 'maven'

      compile fileTree(dir: 'libs', include: ['*.jar'])
  }

          mavenCentral()
      }

  <p>There is nothing wrong with that, or any other test, as it has not changed in months.  In fact, the problem seems to have started when I added the two jar files to the project.  However, I have not been able to find an answer to this particular error message anywhere.</p>
