gwt-maven-plugin：编译失败“状态为 1”答案

【问题标题】：gwt-maven-plugin: Compile fails "with status 1"gwt-maven-plugin：编译失败“状态为 1”

【问题描述】：

我从事 GWT 项目已经有一段时间了，我相信自从我添加了新的依赖项后，我得到了以下错误。

未能在项目项目上执行目标 org.codehaus.mojo:gwt-maven-plugin:2.6.1:compile（默认）：命令 [[

/bin/sh -c /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java -Xmx512m -classpath /home/user/git/project/target/project-0.0.1- SNAPSHOT/WEB-INF/classes:/home/user/.m2/repository/A.jar:/home/user/.m2/repository/B.jar:... 更多的依赖项 ... com.google.gwt.dev.Compiler -logLevel INFO -style OBF -war /home/user/git/project/target/project-0.0.1-SNAPSHOT -localWorkers 1 -XfragmentCount -1 -sourceLevel 1.6 -gen /home/user/git/project/target/.generated my.project.Project

当我在 Windows 7 上运行错误中给出的命令时，我得到“输入太长”。
当我在 Ubuntu 上运行命令时，没有显示错误。 echo $? 但显示返回状态为 1。

mvn package -X 给出的堆栈跟踪看起来像

【问题讨论】：

GWT 编译器前面的输出/日志中真的没有输出吗？（一般在成功构建或失败的模块总结之前）
我通过运行mvn package 更新了 eclispe 控制台中显示的输出。这有帮助吗？我也弄错了：在 ubuntu 上，该命令也返回 1，尽管我在它的输出中没有发现明显的错误。

【解决方案1】：

我跑了 mvn package -X 发现如下错误

[INFO] [ERROR] Errors in 'gwtupload/client/DecoratedFileUpload.java' [INFO] [ERROR] Line 371: Rebind result 'gwtupload.client.DecoratedFileUpload.DecoratedFileUploadImpl' cannot be abstract

所以我将依赖项 gwtupload 更新为解决了我的问题的新版本。

我在之前的尝试中忽略了这个错误的原因是 mvn package 之前成功了，在这个特定版本中使用了这个依赖项。所以我想这个错误一定一直存在，仍然导致打包成功。

感谢 maven 的 Debug 标志建议，我们遇到了类似的 gwt 错误，遗憾的是最终异常没有正确的错误

【解决方案2】：

当 MVN 在 Cygwyn 32 位版本中构建 Vaadin 项目时，我遇到了类似的问题。但是当我切换到 Cygwyn 64 位时，这个问题就解决了。
