私はモジュールごとにjaxb2-maven-pluginを使用してxjcでXSDファイルをコンパイルします。ここで、モジュールがA→Bの順番でコンパイルされたとします。すべてが正常に動作するために（つまり、私は* XsdImpl.javaを得る）が、BIを得るために、以下：jaxb2 mavenプラグインは2回目の実行時には機能しません

モジュールの両方がプラグインのために同じ設定を使用します2番目のモジュール（AまたはBのどちらでもかまいません）のために常に来ます。 私は舞台裏で何が起こるかを把握しようと多くの時間を費やしてきたが、残念ながら成功せず... は例えば、私はここで最初の実行時に何が起こるのかを理解したいと思います：
at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source)
--->>> at org.xml.sax.helpers.XMLFilterImpl.parse(XMLFilterImpl.java:333)
I org.apache.xerces.jaxp.SAXParserImplの代わりに別のクラスが使用されていると推測されますが、何とかorg.apache.xerces.jaxp.SAXParserImplが2回目に選択されています。これをどのように証明できますか？誰かがすでに同じ問題を経験したのですか？
事前にヒント/助けをいただきありがとうございます！ さようなら
これは、検索の多くを取り、これは最終的にも私のために同じエラーを解決するソリューションでした。 xercesの ' 2.11.0 'を使用しています。私はxml-apisを省略でき、v1.4.01に解決しました –
