pom.xmlが無視される

Ivyでは多くの場合、依存をmaven2リポジトリ上から取得してくるが、そのpom.xmlはIvyの形式(ivy.xml)に自動変換されてivyキャッシュに格納される。例えば、プロジェクト中でguice-2.0への依存を宣言すると、ivyはmaven2リポジトリからそれを取得し、以「${user.home}/.ivy2/cache/com.google.inject/guice」に以下を作成する。

  • ivy-2.0.xml.original ... オリジナルのguiceのpom.xmlファイル
  • ivy-2.0.xml ... 上をivy.xmlに自動変換したもの。
  • jars ... guice-2.0のjarファイルを格納するフォルダ
  • ivydata-2.0.properties ... 今のところ用途不明

ivy-2.0.xmlは以下のようになる。

                <conf name="system" visibility="public" description="this scope is similar to provided except that you have to provide the JAR which contains it explicitly. The artifact is always available and is not looked up in a repository."/>
                <conf name="sources" visibility="public" description="this configuration contains the source artifact of this module, if any."/>
                <conf name="javadoc" visibility="public" description="this configuration contains the javadoc artifact of this module, if any."/>

        </configurations>
        <publications>
                <artifact name="guice" type="jar" ext="jar" conf="master"/>
        </publications>
        <dependencies>
                <dependency org="aopalliance" name="aopalliance" rev="1.0" force="true" conf="compile->compile(*),master(*);runtime->runtime(*)"/>
                <override org="com.google.inject" module="guice" matcher="exact" rev="2.0"/>
                <override org="aopalliance" module="aopalliance" matcher="exact" rev="1.0"/>
        </dependencies>
</ivy-module>

このように、dependencies部分に正しくaopallianceへの依存が記述されている。 これがうまくいかない場合がある。アーティファクトのjarは取得できるものの、pom.xmlが取得できないため、ivyはこのアーティファクトについては勝手にデフォルトのivy.xmlを作成してしまい、そのアーティファクトの依存（現在のプロジェクトから見ると推移的依存）が抜け落ちてしまうことがある。 

<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0">
        <info organisation="xxxx"
                module="xxxx"
                revision="0.1.3"
                status="release"
                publication="20100922230141"
                default="true"
        />
        <configurations>
                <conf name="default" visibility="public"/>
        </configurations>
        <publications>
                <artifact name="xxxx" type="jar" ext="jar" conf="default"/>
        </publications>
</ivy-module>

このケースはivysettings.xmlのリゾルバ指定の問題と思われる。このときの、ivyの出力を観察してみると （ivy/IvyDE/consoleの訳注のやり方でチェック）、以下のような出力が見られる。

最後の「no ivy file found for clog#clog;0.1.3: using default data」がこの状態を示している。
