Java net.sf.jasperreports.engine.JRRuntimeException:无法加载以下字体

我的应用程序使用JasperReports生成PDF文件。我使用Assembly Maven插件为我的应用程序生成一个jar

问题是，当我使用命令行

java-cp“PrintOutCore-1.0.jar”com.soprabanking.printout.Launcher运行jar时，我得到以下异常：

net.sf.jasperreports.engine.JRRuntimeException:无法加载以下字体：
PDF名称：DejaVu Sans
pdf编码：Identity-H
isPdfEmbedded：正确
位于net.sf.jasperreports.engine.export.JRPdfExporter.getFont（JRPdfExporter.java:2176）
位于net.sf.jasperreports.engine.export.JRPdfExporter.getChunk（JRPdfExporter.java:1967）
位于net.sf.jasperreports.engine.export.JRPdfExporter.getPhrase（JRPdfExporter.java:1936）
...

但是，当我使用命令行
java-cp“jasperreports-fonts-4.0.0.jar；PrintOutCore-1.0.jar”com.soprabanking.printout.Launcher
将jasperreports字体jar添加到类路径时，问题消失了，一切正常

如何正确运行jar而不在命令行中手动将jasperreports字体jar添加到类路径

这是我的pom.xml：

经过长时间的搜索，我找到了问题的根源

事实上，在打包时，程序集插件会两次找到文件jasperreports\u extension.properties，因此它会删除一个并保留另一个

一个解决方案是用Maven Shade插件替换Maven Assembly插件，并向其添加一个转换器
