Vaadin 7 Beta 11 GWT Error with Ivy and Eclipse experimental plugin

[The_Vaadin (The Vaadin Guy)]

I am using Vaadin 7 beta 11 and using Eclipse Vaadin plugin and Ivy plugins as explained here (https://vaadin.com/book/vaadin7/-/page/getting-started.eclipse.html)

When I try to compile widgets, I get the following error. PLEASE HELP!

where 
  -logLevel                The level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL
  -workDir                 The compiler's working directory for internal use (must be writeable; defaults to a system temp dir)
  -gen                     Debugging: causes normally-transient generated types to be saved in the specified directory

, PRETTY, or DETAILED (defaults to OBF)
  -ea                      Debugging: causes the compiled output to check assert statements
  -XdisableClassMetadata   EXPERIMENTAL: Disables some java.lang.Class methods (e.g. getName())
  -XdisableCastChecking    EXPERIMENTAL: Disables run-time checking of cast operations
  -validateOnly            Validate all source code, but do not compile
  -draftCompile            Enable faster, but less-optimized, compilations
  -optimize                Sets the optimization level used by the compiler.  0=none 9=maximum.

  -strict                  Only succeed if no input files have errors
  -XenableClosureCompiler  EXPERIMENTAL: Enables Closure Compiler optimizations
  -XfragmentMerge          DEPRECATED (use -XfragmentCount instead): Enables Fragment merging code splitter.
  -XfragmentCount          EXPERIMENTAL: Limits of number of fragments using a code splitter that merges split points.
  -localWorkers            The number of local workers to use when compiling permutations
  -war                     The directory into which deployable output files will be written (defaults to 'war')
  -deploy                  The directory into which deployable but not servable output files will be written (defaults to 'WEB-INF/deploy' under the -war directory/jar, and may be the same as the -extra directory/jar)
  -extra                   The directory into which extra files, not intended for deployment, will be written
and 
  module[s]
                Specifies the name(s) of the module(s) to compile

An upgrade to the latest experimental version of the Eclipse plug-in should help (update site http://vaadin.com/eclipse/experimental).

@Henri Sara

An upgrade to the latest experimental version of the Eclipse plug-in should help (update site http://vaadin.com/eclipse/experimental).

I´ve got the same error, but updating to the latest experimental version of the Eclipse plug-in did NOT help.

I had the same error. Solved with Vaadin Eclipse Plugin upgrade - to version: 2.0.1.201212190201.

@Peter M

I had the same error. Solved with Vaadin Eclipse Plugin upgrade - to version: 2.0.1.201212190201.

I´m using exactly that version, but the result is still:

Any other ideas?

One more thing to check: make sure that the Ivy dependencies for the project have been resolved.
Unresolved dependencies could cause the wrong compiler version to be selected when the plug-in does not find the new JARs.

[Artur (Artur Signell)]

You should check that you do not have anything extra on your classpath aswell. Your inclusion of C:/Java-Projekte/Eclipse/AdSuite/runtime/lib/vaadin7/gwt-dev.jar looks a bit suspicious and will likely cause conflicts with the GWT classes in vaadin-client-compiler and vaadin-client.

[Stefan98 (Stefan Plaß)]

Artur & Henri,

thanks for your answers!

I´m not using ivy - I prefer having all my jars at hand, thus knowing what I´ll have to deploy for delivery - maybe I don´t know enough about ivy?

Your definitely right with your classpath assumption: If I create a new project from the scratch, creating the widget set using the vaadin eclipse plug-in works properly, so it´s obviously an issue with our classpath. I know this classpath is kind of huge - it´s the result of a large project evolving over 9 years, having to include tons of new features every few months. By the way, Vaadin to me seems to be the first technology we can use to get a huge part of our existing functionality into a web application.

I now created a shell script file for compiling my widget set with an adapted classpath, and this works perfectly.

Merry Christmas,
Stefan

Removing the following dependency from the pom.xml solves the above problem for me.

		<dependency>
			<groupId>com.google.gwt</groupId>
			<artifactId>gwt-dev</artifactId>
			<version>2.4.0</version>
		</dependency>
