[tycho-user] Warning when building feature

[motes motes <mort.motes@xxxxxxxxx>]

I build a feature using tycho:

<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>com.test</groupId>
    <artifactId>main.parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../com.test.main.parent</relativePath>
  </parent>

  <artifactId>a.feature</artifactId>
  <packaging>eclipse-feature</packaging>

</project>

[INFO] --- tycho-p2-plugin:0.12.0:feature-p2-metadata
(default-feature-p2-metadata) @ a.feature ---
[WARNING] C:\workspace\com.test.a.feature\target\site does not exist
or is not a directory

Is it safe to avoid this warning and why is it posted?

Previously I created a deployable feature (which create the site folder):

      <plugin>
        <groupId>${tycho-groupId}</groupId>
        <artifactId>tycho-packaging-plugin</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <deployableFeature>true</deployableFeature>
        </configuration>
      </plugin>

but after upgrading to use eclipse-repository for publishing my
features I no longer use that.
