My first results when building Apache Maven 3.3.7-SNAPSHOT
Without extra configuration it fails with the message:
No compiler is provided in this environment. Perhaps you are running
on a
JRE rather than a JDK?
However, if I add the following arguments it at least continues:
-Dmaven.compiler.executable=D:\jdk1.9.0\bin\javac.exe
-Dmaven.compiler.fork
So this is something we need to fix on our side. If I recall correctly
we
do a tools.jar check somewhere, will require some extra investigation.
The build doesn't complete, it fails with the exception below, but
according to the message we need an improved version from ASM first.
best,
Robert

Hi Robert & Kristian,
Early-access builds of JDK 9 with Project Jigsaw are available for
download at jdk9.java.net/jigsaw <http://jdk9.java.net/jigsaw>.
The EA builds contain the latest prototype implementation of JSR 376
<http://openjdk.java.net/projects/jigsaw/spec>, the Java Platform
Module
System,
as well as that of the JDK-specific APIs and tools described in JEP
261
<http://openjdk.java.net/jeps/261>.
If you'd like to try out the EA builds, by far the most helpful things
you can do are:
*
Try to run existing applications, without change, on these builds
to
see whether the module system, or the modularization of the
platform, breaks your code or identifies code that depends upon
JDK-internal APIs or other unspecified aspects of the platform.
*
Experiment with the module system itself, perhaps by following the
quick start guide
<http://openjdk.java.net/projects/jigsaw/quick-start>, and start
thinking about how to migrate existing libraries and application
components to modules. We hope to publish some specific migration
tips shortly.
Please send usage questions and experience reports to the jigsaw-dev
<http://mail.openjdk.java.net/mailman/listinfo/jigsaw-dev> list.
Specific suggestions about the design of the module system should be
sent to the JSR 376 Expert Group's comments list
<mailto:[email protected]>.
For more information please seen Mark Reinhold's mail [1]
Rgds,Rory
