 			Note, to tell the <code>gradle-lombok</code> plugin to use the latest version of lombok, you need to explicitly tell it about the latest version number and the SHA-256. For our current latest version, put this in your <code>build.gradle</code> file:<pre>
 lombok {
-	version = ${version} 
+	version = '${version}'
 	sha256 = ""
 }</pre>
