eclipse - 无法从 maven 获取 datanuecleus 3.1.3
问题描述
试图解决错误
Exception in thread "main" java.lang.IncompatibleClassChangeError: Implementing class
我发现有几篇文章解释了这可能是由于使用了不兼容的 datanueclus 依赖项版本造成的。
所以我降级了一些我用来使用我认为兼容的版本的版本(请参阅下面的 pom.xml)但我的问题是 maven 没有为我获得 datanueclus-core 3.1.3。即使我特别要求 3.1.3,它也只会获得最新版本 5.2.5
我该如何解决这个问题?如果我要求 5.2.4,它会毫无问题地得到那个。但如果我尝试获得 3.1.3,它只会获得最新的。

请同时检查我的版本是否兼容。我尝试遵循此https://code.google.com/archive/p/datanucleus-appengine/wikis/Compatibility.wiki但我不确定我是否理解。
提前致谢
解决方案
听起来其他一些依赖项具有版本 5.2.4 作为依赖项。
在您的<dependencyManagement>
部分中,您需要强制版本,如下所示:
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-maven-plugin</artifactId>
<version>3.2.0-m2</version>
</dependency>
在您的常规<dependencies>
部分中,您应该指定没有版本的工件,如下所示:
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-maven-plugin</artifactId>
</dependency>
