Ben DeLillo updated MWAR-439:
-----------------------------
Description:
I don't have a distributable repro case, but I can say that in my multi-module
project, when the exploded goal is invoked by eclipse the following error
occurs:
{code:java}
Execution default of goal
org.apache.maven.plugins:maven-war-plugin:3.3.1:exploded failed.
(org.apache.maven.plugins:maven-war-plugin:3.3.1:exploded:default:process-resources)
{code}
The stack trace for this error is
{code:java}

session.getStartTime() is null, so the call to getTime() throws an NPE.
Attempting to track down why the start time is null led me to MavenImpl, at
which point I've gotten a bit stuck trying to further track down the issue. I
think it was pointing to something in MavenExecutionContext, but I'm not
entirely sure.
The check against getStartTime was introduced in 3.3.1 so switching to 3.3.0
unblocks me for now.
