buildr use optional transitive artifact dependency

How can Apache Buildr be told to follow dependencies with <optional>true</optional> in the pom?开发者_Go百科 See the related question at Trouble getting Hibernate Core and Hibernate Annotations using Apache Ivy (but it's also Maven2 related.)

Thank you.

i'm afraid that transitive support is experimental in buildr, there are a few problems with it. Tou could try listing the dependencies by hand:

HIBERNATE = ["mysql:mysql-connector-java:jar:5.1.13",
         "org.hibernate:hibernate-core:jar:3.5.5-Final",
         "antlr:antlr:jar:2.7.6",
         "commons-collections:commons-collections:jar:3.1",
         "commons-pool:commons-pool:jar:1.5.4",
         "commons-dbcp:commons-dbcp:jar:1.3",
         "commons-lang:commons-lang:jar:2.5",
         "dom4j:dom4j:jar:1.6.1",
         "xml-apis:xml-apis:jar:1.0.b2",
