libraryDependencies中的revisionId如何成为SBT 0.13+中最新的可用版本？

Question

How can I set the revisionId of the libraryDependencies setting to the latest available version in SBT 0.13+ . I was using "*" but didn't seem to work, eg:

"org.eclipse.jetty" % "jetty-webapp" % "*"

Answer 1

SBT uses Ivy for dependency resolution, so it supports Ivy's dynamic revision syntax:

• 9.0.+ will match any version like 9.0.0 or 9.0.7 ,
• latest.release will match the most recent release,
• [9.0,) matches all versions greater or equal to 9.0 , like for example 9.1.0 ,
• [9.0,9.1[ matches all versions greater or equal to 9.0 and strictly below 9.1 ,
• and so on... : Ivy dynamic revision syntax

By default SBT will pick the latest available revision in a range, even in case of a dependency conflict, but this can be customized .
