There is an issue with the helidon-tags, these modules are not intended in the reactor.

[barchetta]

Workaround:

1. Edit top level pom.xml
2. Remove these two lines:

    <module>quickstart-se</module>
    <module>quickstart-mp</module>

[romain-grecourt]

I've manually fixed-up all the tags, @barchetta will take care of fixing the build scripts to make sure this does not happen for future releases.

@barchetta I have tried this way, some tests are failed in my local system. I was using -Dmaven.test.skip=true -DskipTests to build it sucessfully.

Another small issue when I build this project locally.

The JDk toolchian version is not defined by default, I am using ~/.m2/toolchains.xml to use multi jdks.

https://github.com/oracle/helidon/blob/master/pom.xml#L1261-L1992

I have to pass a maven.compiler.target to mvn command to make it work.

[romain-grecourt]

The toolchains profile is incomplete, IIRC @ljnelson had some changes to make it work.
If possible share the failed tests so that we can track that in a specific issue.

@romain-grecourt created #72

Regarding toolchains: the maven.compiler.target property is never set. You can use a toolchain more reliably, I think, by doing, e.g., mvn clean install -DjdkToolchainVersion=8. See also:
