Drools Eclipse plugin can't recognize third party classes --------------------------------------------------------- Key: DROOLS-472 URL: https://issues.jboss.org/browse/DROOLS-472 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Environment: * OS: Mac OS X 10.9.2 * Eclipse Kepler * Drool Eclipse Plugin - JBoss Drools Core 6.0.1Final. (I don't have problem with Drools Core 5.6.0Final) * Java SE 1.7 * Drools Runtime 6.0.1 Reporter: Jinghai Rao Assignee: Mario Fusco Fix For: 6.1.0.CR1 Whenever I use classes from any third party jar files (not in JRE System Library and Drools Library), I got error messages in Eclipse IDE. At the place where I import the class, the error message is "Only a type can be imported. ... resolves to a package". At the place where I use the class, the error message is "... cannot be resolved to a type". However, I have included the jar file in classpath. The project can also be executed successfully even with the error message in IDE. Below is my development environment: * OS: Mac OS X 10.9.2 * Eclipse Kepler * Drool Eclipse Plugin - JBoss Drools Core 6.0.1Final. (I don't have problem with Drools Core 5.6.0Final) * Java SE 1.7 * Drools Runtime 6.0.1 !https://lh5.googleusercontent.com/-gltHnzUIUg4/U1qbEzVd_LI/AAAAAAAAEYw/mKxE2jv-VVc/w1796-h1168-no/Screen+Shot+2014-04-25+at+10.20.36+AM.png!
