Relates(Same as) issue IDEADEV-23941 I'm developing a Pluging using maven for dependencie management. The problems has been explained on this - http://www.intellij.net/forums/thread.jspa?threadID=271574&tstart=0 - forum thread and originated IDEADEV-23941 issue that is now marked resolved on version 7.0.3. I'm using IDEA version 7.0.4 and having the exact same problem. IDEA is ignoring the scope tag on my POM file and copies the jar's to the plugin-sandbox\lib dir. It's also ignoring transitive exclusions . Ex : <dependency> <groupId>com.logical.loomy</groupId> <artifactId>core</artifactId> <version>1.0-SNAPSHOT</version> <exclusions> <!-- Excludes xmlrpc transitive dep from loomy:core because xmlrpc is present in the IDEA SDK --> <exclusion> <groupId>xmlrpc</groupId> <artifactId>xmlrpc</artifactId> </exclusion> <!-- Excludes velocity transitive dep from loomy:core because velocity is present in the IDEA SDK --> <exclusion> <groupId>org.apache.velocity</groupId> <artifactId>velocity</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>5.1</version> <classifier>jdk15</classifier> <scope>test</scope> </dependency> <dependency> <groupId>org.easymock</groupId> <artifactId>easymock</artifactId> <version>2.3</version> <scope>test</scope> </dependency> <dependency> <groupId>org.easymock</groupId> <artifactId>easymockclassextension</artifactId> <version>2.2.2</version> <scope>test</scope> </dependency> Copied jar's in the plugin-sandbox lib dir lib/annotations-1.0.0.jar lib/axis-1.3.jar lib/axis-jaxrpc-1.3.jar lib/xis-saaj-1.3.jar lib/cglib-nodep-2.1_3.jar lib/client-1.0-SNAPSHOT.jar lib/cobra-0.98.3.jar lib/commons-chain-1.2.jar lib/commons-collections-3.1.jar lib/commons-discovery-0.2.jar lib/commons-lang-2.1.jar lib/commons-logging-1.0.4.jar lib/easymock-2.3.jar --> MARKED WITH SCOPE TEST lib/easymockclassextension-2.2.2.jar --> MARKED WITH SCOPE TEST lib/jira-ws-client-1.0-SNAPSHOT.jar lib/js-0.98.3.jar lib/junit-3.8.1.jar --> MARKED WITH SCOPE TEST lib/maven-model-2.0.7.jar lib/oro-2.0.8.jar lib/plexus-utils-1.4.1.jar lib/testng-5.1-jdk15.jar --> MARKED WITH SCOPE TEST lib/tools.jar lib/velocity-1.5.jar --> MARKED WITH EXCLUDE lib/wsdl4j-1.5.1.jar lib/xmlunit-1.1.jar --> MARKED WITH SCOPE TEST
