eclipse：JSF 2ファセットの結果をNullpointerExceptionに追加する

Question

私はmavenプロジェクトを持っており、JSF 2ファセットをプロジェクトに有効にしたいと思います。なぜなら、jsf/primefacesタグ自分のjsfページを編集するときにタグ属性をctrlスペースで使用します。

..か..おそらく他のいくつかの方法がありますEclipse Heliosの動的Webモジュールとjsf 2ファセットを追加せずに自動補完を有効にするには？

Answer 1

自分で解決策を見つけました。私はただプロジェクトを削除し、mavenプロジェクトとして再インポートし、ファセットを追加して、最終的にはすべて正常です。

ありがとうございます！今はとても幸せです。うまくいけば、これは他人を助けることもできます。
