mvn site:siteでやたらスタックトレースが出力される
はじめに
実用上問題ないのですが、mvn site:siteを実行するとスタックトレースがいっぱい出力されます。
無視して良いのか気になったので調べてみました。
事象
mvn site:site実行時に以下のようなスタックトレースが出力されます。

[WARNING] Unable to create Maven project from repository for artifact jaxen:jaxen:jar:1.1.1
(中略)
原因
mvn-site-plugin中にdistributionManagement.statusの値のチェックがあるのが原因です。
以下に説明が載っています。
http://maven.40175.n5.nabble.com/Trying-to-fix-integration-tests-of-mvn-site-plugin-td5950400.html
.m2/repository/jaxen/jaxen/1.1.1/jaxen-1.1.1.pomをみてみたら、以下の記述がありました。
これのstatus要素がチェックに引っかかってるんですね。
<distributionManagement> <repository> <id>default</id> <name>Default Repository</name> <url>file:///dist</url> </repository> <site> <id>default</id> <name>Default Site</name> <url>scp://jaxen.codehaus.org//home/projects/jaxen/public_html</url> </site> <status>converted</status> </distributionManagement>jaxen-1.1.1.pomを直接編集してstatus要素を消すと、このスタックトレースは出なくなります。
どう対策する？
現状ではこのスタックトレースが出るのは無視するのが良さそうです。
前述のhttp://maven.40175.n5.nabble.com/Trying-to-fix-integration-tests-of-mvn-site-plugin-td5950400.htmlをみるといつかはApache Maven Site Pluginが治りそうですが、まだ治ったバージョンはリリースされていないためです。
さいごに
設定ミスったのかなーと最初は不安に思っていたのですが、そうじゃなかったので安心しました。
