maven iReport项目中的java.lang.String cannot be resolved编译错误
maven iReport项目中的java.lang.String cannot be resolved编译错误
提问于 2020-02-22 01:59:48
也许有人能帮我解决这个问题。我试图将iReport集成到我的NetBeans项目中，但无法解决以下问题。当我从"MyProject ->新的-->空的报告“中创建新的报表时，它不会编译并显示report选项卡中的预览视图，它会给出以下错误：
编译异常:com.jaspersoft.ireport.designer.compiler.ErrorsCollector@3d50d9ef net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:204) net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1.The type java.lang.String cannot be resolved. It is indirectly referenced from required .class files /* ^1)
同时，如果我在iReport欢迎屏幕上用NetBeans创建新的报告，一切看起来都很好。这是我的档案。

我还将JRE的级别从8降到了JRE 7，在库中为iReport添加了大量文件。从报表查询中可以得到同样的错误。它连接到数据库，但无法从中读取。
有什么想法我在我的项目中遗漏了什么？
提前谢谢你。

我不知道该怎么解释，但这对我来说很管用。转到report属性，然后将语言更改为groovy。在我将语言更改为java之前，会出现这样的错误。
