我正在尝试将 maven 集成到我现有的 Vaadin 项目中。有几个错误和奇怪的事情。首先，我不明白我应该怎么做才能使 maven 使用的 tomcat 实例在 eclipse 中可见。我的意思是，当我运行 tomcat7:run 时，在 eclipse 中预先配置的 Tomcat 实例保持停止。我也无法理解 maven 使用哪个 Tomcat 实例以及为什么它在项目文件夹中创建 Tomcat 配置文件，因为当我尝试在 tomcat7:run 之后在浏览器中打开应用程序时，我收到错误 404。
顺便说一下，有几个关于Vaadin 小部件的编译。我配置了 vaadin maven 插件和 gwt maven 插件。当我运行 mvn gwt:compile 时，似乎一切正常，但是当我尝试使用 eclipse 插件编译 Vaadin 小部件时，出现以下错误

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
-style Script output style: OBF[USCATED], 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.
-compileReport Create a compile report that tells the Story of Your Compile
-strict Only succeed if no input files have errors
-out The directory to write output files into (defaults to current)
-localWorkers The number of local workers to use when compiling permutations
and
module[s] Specifies the name(s) of the module(s) to compile
Widgetset compilation failed
否则，如果我使用 mvn gwt:compile 编译小部件，然后使用 maven 构建战争并部署它，我会在浏览器中收到空白页面。
此外，当我尝试在服务器上运行应用程序时，我有以下异常
