ジャック依存のためにカスタムプロセッサビルドが失敗する

Question

jackson jsonライブラリを使用したカスタムプロセッサを作成し、ユニットテストがうまく動作しました。

ターゲットnarを作成するために構築するプロジェクト/モジュールについて少し混乱します。

プロセッサののpom.xml（Mavenの）プロジェクトは次のとおりです。

はあなたがあなたのプロセッサ（Mavenの）プロジェクトpom.xmlに以下の依存関係を追加する必要があります：

<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-core</artifactId> 
    <version>2.7.8</version> 
</dependency>
