我突然收到一条错误消息，缺少 3 个依赖项：gwt-user.jar、gwt-dev.jar 和 gxt.jar。所有罐子都在我的本地仓库中：

我没有进行任何 maven 更改，并且 pom 也没有更改。我刚刚添加和修改了 java/css/hml 文件。任何想法，有什么问题？
编辑：确切的消息是
Missing:
----------
1) com.google.gwt:gwt-user:jar:2.0.0
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=com.google.gwt -DartifactId=gwt-user -Dversion=2.0.0 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.google.gwt -DartifactId=gwt-user -Dversion=2.0.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

我在命令行中构建项目。
