【问题描述】：
我有一个让我发疯的问题：Tycho 忽略了我添加到 POM 的所有 p2 存储库。以下是 POM 的相关部分：
<properties>
<tycho-version>0.13.0</tycho-version>

<repository>

<layout>p2</layout>

在输出中，我从未看到 [INFO] Resolving target platform for project MavenProject 或 [INFO] Adding repository @987654321@
为什么不呢？如果我从http://git.eclipse.org/gitroot/tycho/org.eclipse.tycho.git 构建第谷，它确实有效，所以它与我的settings.xml 无关。我还尝试了 Tycho 0.12.0，结果相同。
我的构建输出中有趣的部分：

如您所见，第谷已被识别，但显示为 indigo (http://download.eclipse.org/releases/indigo, disabled)。为什么？
