Java Maven Jasperreport 从 Eclipse 运行 好的，从 java - jar JRRuntimeException : Chart theme "eye.candy.sixties" not found

Question

我创建了一个 Java 程序，它使用 JasperReports 创建报告。在我的 JasperReports 之一中，我使用 theme="eye.candy.sixties"。

当我在 gui 中从 Eclipse 运行项目时，一切都很好，请参阅

但是，当我使用 Maven 构建相同的项目并从命令行运行它时，我收到错误:

Maven: clean compile assembly:single
Command line: java -jar chartTheme-0.0.1-SNAPSHOT-jar-with-dependencies.jar

Exception in thread "main" net.sf.jasperreports.engine.JRRuntimeException: Chart theme "eye.candy.sixties" not found.

我错过了什么，我应该改变什么？欢迎任何帮助!

源代码可以在Github上找到:ChartTheme

我确实在 Maven 中包含了图表主题依赖项，请参阅“Eclipse 中的 Maven 依赖项列表:

并在下面的代码中(pom.xml)

Answer 1

如果您打开构建的联合库 chartTheme-0.0.1-SNAPSHOT-jar-with-dependency.jar，您会发现文件 jasperreports-char- 的内容theme-6.4.0.jar/jasperreports_extension.properties缺失，因为它们被您的其他jasperreports_extension.properties文件的内容覆盖。依赖关系。

事实上，如果您在运行 mvn assembly 后在输出控制台中进行搜索，您会发现以下痕迹:

[INFO] jasperreports_extension.properties already added, skipping

...顺便说一句，这并不是汇编时跳过的唯一一个文件。

因此，由于存在重叠，将所有这些依赖项组装在一起绝对不是一个好主意。至少，不是这样。

我认为您应该尝试的第一件事是参数化 assembly descriptor file排除不需要的文件，优先考虑所需的文件，我认为这些文件将是 jasperreports-chart-themes.jar 中的文件(通过您发布的日志中的跟踪)。
