------------------------------------
Summary: Support Guava version 21.0
Key: CALCITE-1590
URL: https://issues.apache.org/jira/browse/CALCITE-1590
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Guava version 21.0 is an important version because it is the first with JDK 8
support (hence lambdas). Make sure that Calcite runs on it (on JDK 8 and
later). Continue to support other versions of Guava as early as 14.0.1.
Compilation using {{mvn clean -Dguava.version=21.0 clean test}} on JDK8
currently yields many errors like the following:
{noformat}
[ERROR] Failed to execute goal
