Thank you to the contributors
First, I want to give a big shout-out and thank you to all the contributors who took time and contributed to this release. This was a minor feature release but there are some notable additions to the library and the Eclipse Collections community. We also have some new first time contributors to Eclipse Collections and OSS, and I want to say congratulations, welcome, and thank you!
- Implemented RichIterable.groupByAndCollect.
public void groupByAndCollect()
MutableList<String> list =
Lists.mutable.with("One", "Two", "Three"); MutableMultimap<Character, String> multimap =
each -> each.charAt(0),
Multimaps.mutable.list.empty()); MutableListMultimap<Character, String> expected =
Multimaps.mutable.list.with('O', "ONE", 'T', "TWO", 'T', "THREE"); Assert.assertEquals(expected, multimap);
2. Implemented NoopProcedure.
public void noopProcedure()
MutableList<Integer> list = Lists.mutable.with(1, 2, 3);
Assert.assertEquals(Lists.mutable.with(1, 2, 3), list);

Four years at the Eclipse Foundation
This month we will celebrate the four year anniversary of Eclipse Collections as a project at the Eclipse Foundation. I am happy to report that Eclipse Collections is still going strong! We continue to grow our community of contributors, users, and advocates. Everyone I know that uses Eclipse Collections in their projects really appreciates the richness and symmetry of the API, and the productivity and performance of the library. Thank you to everyone in the Eclipse Collections community for your support!
Eclipse Collections 10.1 will also be included in the upcoming Eclipse IDE release.
Note: Eclipse Collections can be used in any Java project and with any Java IDE. Eclipse Collections has no runtime dependencies on any other library and does not depend on the Eclipse IDE. The library is available in Maven Central and as an OSGi Bundle.
