javanet。旧金山。jasperreports。发动机JRuntimeException: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，会出现以下异常：
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)
...
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:

# 1 楼答案
经过长时间的搜索，我找到了问题的根源
实际上，在打包时，程序集插件会找到文件jasperreports\u扩展名。属性两次，因此它删除一个，保留另一个
解决方案是用Maven Shade插件替换Maven Assembly插件，并为其添加一个转换器
