[undertow-dev] Compile error on clean checkout

Undertow, I was trying to do a fresh pull and build of Undertow. I've tried on both the master branch and on the 1.2.x series. Both of them fail the compile goal with different errors. From master I get [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project undertow-servlet: Compilation failure [ERROR] /home/greg/build/undertow/servlet/src/main/java/io/undertow/servlet/spec/ServletPrintWriterDelegate.java:[28,99] incompatible types: java.lang.reflect.Constructor<capture#1 of ?> cannot be converted to java.lang.reflect.Constructor<io.undertow.servlet.spec.ServletPrintWriterDelegate> [ERROR] Failed to execute goal on project undertow-servlet: Could not resolve dependencies for project io.undertow:undertow-servlet:jar:1.2.6.Final-SNAPSHOT: Failure to find io.undertow:undertow-core:jar:tests:1.2.6.Final-SNAPSHOT in http://repository.jboss.org/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of jboss-public-repository-group has elapsed or updates are forced -> [Help 1] I'm building this on Fedora 21 with Java 1.8.0_31 OpenJDK and Maven 3.2.2, both from the Fedora yum repositories. I get very similar errors trying to build on Windows 8.1 with Java 8 and Mavent 3.2.5. I can't help but imagine there is some environmental setup step that I'm missing. Is there any pointer to documentation around getting a development environment configured that I'm missing? Thanks! --Greg
