gwt-maven-plugin：编译失败“状态 1”

我已经在 GWT 项目上工作了一段时间，并且我相信自从添加了新的依赖项后，我收到了以下错误。

无法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/类：/home/user/.m2/repository/A.jar:/home/user/.m2/repository/B.jar:...更多的依赖... 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

1. 当我在 Windows 7 上运行错误中给出的命令时，我收到“输入太长”。
2. 当我在 Ubuntu 上运行该命令时，没有显示任何错误。echo $?但显示返回状态为 1。

给出的堆栈跟踪mvn package -X好像

我运行 mvn package -X 并发现以下错误

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

所以我更新了依赖项gwtupload到解决我的问题的新版本。

我在之前的尝试中忽略此错误的原因是mvn package之前是成功的，在此特定版本中使用此依赖项。所以我想这个错误一定一直存在，仍然导致打包成功。
