[numbers-fraction] Maven surefire plugin error

Eric Barnhill
I am getting a maven error for the surefire plugin, but don't see it listed
as a dependency in numbers-fraction or numbers-core. I see it listed in
numbers-parent, but with no version number. Any ideas what I need to do to
get the tests running again?

I also get this error with other numbers modules so I suspect it is down to
my setup, but just can't quite see what to modify. "It was all working last
week..."

Error msg:
---
Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test (default-test)
on project commons-numbers-fraction: Execution default-test of goal
org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test failed.

Re: [numbers-fraction] Maven surefire plugin error

I just did a fresh clone of commons-numbers and it runs ‘mvn test’ ok.

Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T20:39:06+01:00)
Maven home: /usr/local/Cellar/maven/3.5.0/libexec
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.3", arch: "x86_64", family: “mac"


The output listed maven-surefire-plugin:2.22.0

Your 2.20.1 version may indicate something is out of sync somewhere.

The effective pom view in eclipse has both versions in properties:

<surefire.version>2.20.1</surefire.version>
<commons.surefire.version>2.22.0</commons.surefire.version>

PluginManagement has:

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.22.0</version>
</plugin>

This seems to be coming from commons-parent 47.

Try a fresh clone and build. Or are you on a branch other than master?

Version is probably inherited from CP (commons-parent).

Did you change the environment (IDE, JVM, maven)?

This does not occur on "master" but only on the "fraction-dev" branch.
Here is an excerpt of the exception trace (from running "mvn -e test"):

I tried the ‘fraction-dev’ branch. My build from the root reactor gets past the [numbers-fraction] module but fails on [numbers-arrays] with a compilation failure.

Since it is possibly a platform issue I'll try open JDK on linux tomorrow for comparison.

You could try updating the branch to commons-parent 47 as a test.

I'd recommend that you regularly rebase from "master".

Rebasing on master fixed the problem, thank you.
