有 Java 编程相关的问题?

你可以在下面搜索框中键入要查询的问题!

java Maven在@XmlAccessorType上抛出编译错误“找不到符号”,但我可以找到它

为什么我的mvn clean install命令告诉我它找不到符号,而它抱怨的类似乎显然是可用的

我正在构建一个库来处理对REST api(HP ALM)的调用。它返回xml,因此我必须解析结果

这个库已经基本完成,并且可以运行,但是现在我想在一个更大的gui应用程序中测试它,所以我需要构建和安装这个库。jar到我当地的maven存储库。图书馆开发过程中没有(相关)错误

下面是我在运行mvn clean install时遇到的错误

现在,我已经读到编译器插件2.3.2可能有一个bug,所以我尝试了该插件的多个其他版本。以下是3.1的回应:

它们都给出了几乎相同的错误。3.1与2.3.2具有相同的行号,但字符索引的变化范围为2->;10.此外,3.1明确指出了导致错误的类。Entity-类是一个标准生成的类,用于解释REST调用的结果。所有结果对象都将采用实体格式

作为参考,这是我的pom。xml。我已经手动检查了jaxb绑定依赖项jar,以检查relevand注释类是否在库中。的确如此

最后但并非最不重要的是实体类(我手动添加了一个toString方法)

This example of an automatically generated class is an example of how one can
generate classes from XSDs via xjc to match jaxb standards.
XSD is a format for describing a class structure
(note: the CLASS not an INSTANCE of the class).
From an XSD one can generate a class java source file.
When compiling this source file, one can "marshal" an actual object instance
from the XML describing the object (this time we are talking about an instance,
not a class).

this process has many advantages, and is a form of serialization that is not
language dependent.
This is the recommended way of working with entities, though we do suggest you
customize your entity class with simpler accessors.

    我也有同样的问题。解决方案是更改导入语句的顺序。在您的情况下,将此导入语句放在最后,然后重新生成
