問題点：
そもそも何故このような現象が起こるかについてですが、jbpm-designer の親にあたる org.kie:kie-parent:7.0.0.Beta6 にチェックが仕込まれています。
C:\Git\jbpm-designer\pom.xml に次のような記述があります：
<parent>
<groupId>org.kie</groupId>
<artifactId>kie-parent</artifactId>
<version>7.0.0.Beta6</version>
<!-- relativePath causes out-of-date problems on hudson slaves -->
<!--<relativePath>../droolsjbpm-build-bootstrap/pom.xml</relativePath>-->
</parent>
<groupId>org.jbpm</groupId>
<artifactId>jbpm-designer</artifactId>
<packaging>pom</packaging>
org.kie:kie-parent:7.0.0.Beta6 を求めて…
わたしの場合は、こちらのファイルに： C:\Users\ku_000\.m2\repository\org\kie\kie-parent\7.0.0.Beta6\kie-parent-7.0.0.Beta6.pom
<execution>
<id>enforce-direct-dependencies</id>

<!-- The marshalling classes are generated by Errai during GWT compilation. These classes
usually contain references to other dependencies which are not part of the project
(transitive dependencies), which then results in the dependency check failure.
From the maintenance point of view, ignoring these generated classes seems like the
best option. -->

対策：
(1) スキップしたい
スキップすることができます。 mvn package -Denforcer.skip=true
参考
スキップできたとしても、デプロイが失敗します。本質的な対策にはなりえません。

(2) 対策したい
不足しているものを調査しないといけません。で、一覧化できます。<dependency> についてくる <version>...</version> は親プロジェクトの pom へ記述するようにし、末端プロジェクトの pom では削除するようにします。

以下、手作業で抽出したもの：
C:\Git\jbpm-designer\jbpm-designer-standalone\pom.xml で、
