Hudson：多模块 Maven 项目的构建失败，然后立即再次成功

Question

我有一个多模块项目，其中顶级项目既充当各个模块的父级项目，又充当声明模块的项目。 Hudson 中仅配置此顶级项目（包括自动 SVN 签出）。简化的布局如下：

ProjectRoot\
|
+---kernel\
|   |
|   +---pom.xml [ArtifactId=MyProject_kernel parent=MyProject]
|
+---model_foo\
|   |
|   +---pom.xml [ArtifactId=MyProject_model_foo, parent=MyProject]
|
+---pom.xml [ArtifactId=MyProject, parent=none]

此外，model_foo 依赖于kernel。

现在，Hudson 会自动发现 kernel 和 model_foo 子项目，并且通常能够很好地构建所有内容。

但是，每次我进行重大更改（例如在 kernel 中创建一个新类并在 model_foo 中使用它）时，我的 model_foo 构建都会失败code>，后跟一个成功的代码。邮件通知的标题为

• Hudson 中构建失败：MyProject » MyProject Model Foo #1545
• Hudson 构建恢复正常：MyProject » MyProject Model Foo #1546

这是为什么？我怀疑这可能与 MyProject pom.xml 既是多模块项目又是其模块的父级这一事实有关，但在更改之前我想知道它是否真的会发生来帮忙。

我使用哈德森2.1.0。

更新

这是 web 模块构建失败的日志（等于上图中的 model_foo）。 MyProject 根项目的构建具有相同的构建号，并且成功。

我去掉了实际的编译器错误，这与新引入的类丢失时完全相同。
