在 spring-hibernate-maven 项目中出错

Question

我在尝试运行项目时收到“找不到类文件 functionContext”错误。它运行没有错误，但是在我编写了一些单元测试并删除它们之后它开始给出这个错误。这是错误堆栈跟踪；

编译错误：

Failure executing javac, but could not parse the error:


An annotation processor threw an uncaught exception.

Answer 1

将jaxen 添加到您的库可解决此问题。

如果您在项目属性中禁用注释处理，它也会开始工作，但是您不能使用 lombok 之类的东西（lombok 会即时生成 getters/setters/hashcode/constructors）。

编辑：Jaxen 托管在 codehouse，但 codehouse 已停产并且 jaxen.org 已过时。上面的链接指向maven仓库，不知道有没有更好的。

Answer 2

您在使用 Netbeans 吗？

如果是这样，请进入项目的构建设置并取消选中“启用注释处理”。

问候

Answer 3

你需要这个依赖：

<!-- https://mvnrepository.com/artifact/jaxen/jaxen -->
<dependency>
    <groupId>jaxen</groupId>
    <artifactId>jaxen</artifactId>
    <version>1.1.1</version>
</dependency>

Answer 4

似乎不知何故，依赖项没有从网络加载。所以我选择了“Build with dependencies”，构建成功了……
