Cannot build JUnit 5 on Microsoft Windows

[PeterWippermann]

Tried to run gradlew clean test, but at least two tests fail although CI status is "green".

:platform-tests:junitPlatformTest

Test failures (2):

BUILD FAILED

Tried to build with Gradle 2.14 as well as 3.0-20160702000020+0000.
Do I have a local problem?

[smoyer64]

I built locally this afternoon as of commit 4aa8827.

[sbrannen]

I have no problems building against the current master.

Can you please share with us the output from ./gradlew -version?

[PeterWippermann]

@sbrannen here it is:

[PeterWippermann]

Regarding your feedback in #397 I switched back to 2.14, but the error stays the same.

Thanks for sharing the Gradle version information.

Since you're building on windows, it is now apparent that it is almost certainly an issue with EOL characters.

Oh the joy of Write Once, Debug Everywhere! 😞

We'll look into it.

[jbduncan]

I know that projects like Checkstyle use AppVeyor to test against Windows VMs (in addition to using TravisCI for Linux coverage). Perhaps using AppVeyor would prevent these sorts of errors cropping up again in the future?

[sbrannen]

AppVeyor (or similar) sounds like a very good idea.

I'll create an issue to track this.

Cheers!
