net.sf.jasperreports.engine.JRRuntimeException：次のフォントをロードできませんでした

Question

私のアプリケーションはJasperReportsを使用してPDFファイルを生成します。 Assembly Mavenプラグインを使用してアプリケーション用のjarファイルを生成します。

問題は、私は、コマンドラインを使用してjarファイルを実行すると、私は次の例外を取得することです：、

net.sf.jasperreports.engine.JRRuntimeException: Could not load the following font: 
pdfFontName: DejaVu Sans 
pdfEncoding: Identity-H 
isPdfEmbedded : true 
    at net.sf.jasperreports.engine.export.JRPdfExporter.getFont(JRPdfExporter.java:2176) 
    at net.sf.jasperreports.engine.export.JRPdfExporter.getChunk(JRPdfExporter.java:1967) 
    at net.sf.jasperreports.engine.export.JRPdfExporter.getPhrase(JRPdfExporter.java:1936) 
    ... 

しかし、私は、コマンドラインjava -cp "jasperreports-fonts-4.0.0.jar;PrintOutCore-1.0.jar" com.soprabanking.printout.Launcherを使用してクラスパスにJasperReportsの-フォントジャーを追加するとき問題は消えて、すべてが大丈夫です。

jasperreports-fonts jarをコマンドラインでクラスパスに手動で追加せずにjarを正しく実行するにはどうすればよいですか？

これは私のpom.xmlです：

Answer 1

検索の長い時間の後、私は、問題の根本を発見しました。

は実際には、パッケージング時にアセンブリプラグインは、二回ファイルにjasperreports_extension.propertiesを見つけるので、1を削除し、他を保ちます。

ソリューションは、のMaven-シェード - プラグインでMavenのアセンブリ・プラグインを交換し、それに変圧器を追加することです。
