java version to build accumulo
I am trying to build accumulo 2.0 (master) to work on a ticket, but I keep getting this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project accumulo-core: Compilation failure: Compilation failure:

[ERROR] (argument mismatch; incompatible parameter types in lambda expression)
Here is my java version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
I can't find anything in the accumulo docs about the java version required, please let me know if I need to upgrade java to build.
Thanks,
Don Resnik

Chris,
Thanks and I appreciate your comment. Turns our Java 8_31 is from 2015, so it was not really reasonable for me to think that would work. Now that I have upgraded java, I have Fluo uno set up with my local repo so I am able to test my accumulo changes easily. I am finishing up my second ticket now and should have it code review today.

1.8 is the minimum required for both the 1.9 branch and the master
branch.
In theory, any 1.8 version should work. We don't specify anything more
specific than 1.8. However, there's nothing we can do about a broken
installation or a buggy version of 1.8 that is later patched to fix a
version that doesn't comply with the 1.8 java specifications. We also
don't do anything to require OpenJDK, Oracle JDK, IBM JDK, or any
other version. If updating your software fixed the issue for you, the
best I can suggest is to keep your build environment up-to-date to
avoid bugs in your build tools.

Jeff,
That worked, thanks.
Should the developer docs list the minimum java version required to build the accumulo version?

Jeff,
I was using ‘mvn package’
I will upgrade java and try again.
Thanks,

Which maven command are you using to build accumulo 2.0?

You can try upgrading java to see if that helps. For reference, my version
is 1.8.0_201.
Which maven command are you using to build accumulo 2.0?
