Tycho忽略p2存储库

Question

我有一个让我抓狂的问题: Tycho会忽略我添加到POM中的所有p2存储库。以下是POM的相关部分：

<properties>
    <tycho-version>0.13.0</tycho-version>
</properties>

<repositories>
    <repository>
        <id>indigo</id>
        <layout>p2</layout>
        <url>http://download.eclipse.org/releases/indigo/</url>
    </repository>
</repositories>

        <properties>

在输出中，我从未看到[INFO] Resolving target platform for project MavenProject或[INFO] Adding repository http://download.eclipse.org/releases/indigo/

为什么不行？如果我从http://git.eclipse.org/gitroot/tycho/org.eclipse.tycho.git构建Tycho，它确实可以工作，所以它与我的settings.xml无关。我也尝试了Tycho 0.12.0，得到了相同的结果。

我构建的输出中有趣的部分：

正如您所看到的，Tycho是可识别的，但它显示为indigo (http://download.eclipse.org/releases/indigo, disabled)。为什么？

Answer 1

Tycho团队的Igor Fedorenko发现了问题。在模块中，我使用了

<packaging>jar</packaging>

而不是

<packaging>eclipse-plugin</packaging>

Answer 2

您是否尝试过启用版本和快照？

<repository>
   <id>indigo</id>
   <layout>p2</layout>
   <url>http://download.eclipse.org/releases/indigo/</url>
   <releases>
      <enabled>true</enabled>
   </releases>
   <snapshots>
      <enabled>true</enabled>
   </snapshots>
</repository>

在调用Maven时，您的命令行是什么？您还说“从github构建Tycho”是否意味着您正在使用m2e中的嵌入式Maven/Tycho？
