这里有几个非常相似的问题，除了它们与 Android 运行/调试配置有关。我正在尝试配置 GWT 应用程序。当我尝试保存属性更改时出现此错误。具体来说，在项目属性 UI 中，我在 Google->Web 应用程序中，我正在尝试取消选中“从该目录启动和部署”。我选中了“此项目有一个 WAR 目录”属性，并且在“WAR 目录”框中有一个有效的文件夹。

该错误说要检查 eclipse 错误日志以获取更多详细信息，所以我做了，但在那里没有太大帮助。这是堆栈跟踪的前几行：

java.lang.IllegalArgumentException: Path for project must have only one segment.

我的工作区路径没有空格；它是 C:\projects\eclipse\workspaces\MyProjectHasNoSpaces

我正在运行日食 Helios；GWT 2.5、java 1.6.0_45、Windows 7、64 位。

Eclipse 项目导入器有时会给出无用的通用错误消息。获得真正错误的可预测方法是打开终端窗口并执行“mvn clean compile”或类似的操作。然后您可能会看到更具体的消息，如下所示：

Users/amrinder/xyz> mvn clean compile
[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]   
[ERROR]   The project xyzabc:[unknown-artifact-id]:1.0 (/Users/amrinder/xyzabc/pom.xml) has 1 error
[ERROR]     'artifactId' is missing. @ line 5, column 15

[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
