那些遇到过的问题

Eclipse Deployment Assembly是否会永久性地修复丢失Maven依赖项？

Ale*_*x R 10 eclipse m2eclipse maven

我有一个与此类似的问题(java.lang.ClassNotFoundException:org.springframework.web.context.ContextLoaderListener),我的情况的区别在于,常见的修复(将Maven依赖项添加到部署程序集)只是暂时的,它会破坏每一个时间我做Maven更新,这不是太频繁,但足以成为一个真正的麻烦.

有永久性修复吗？

每次我进行Maven更新时,我都需要手动重复所有步骤来修复Web部署程序集.我实际上已经有几个月的问题了.任何建议,将不胜感激.

Tun*_*aki 7

这种问题通过以下方式解决:

  • 获取最新版本的Eclipse IDE for Java EE Developers.截至今天,这是Eclipse Mars 4.5.请务必选择64位版本(如果您的计算机是64位)并安装最新的64位JDK(截至今天,这是jdk-8u60).
  • 通过在Preferences("Java> Installed JREs")中选择已安装的JDK,在Eclipse中正确设置JRE.
  • 拥有最新m2e和m2e-wtp插件.这是通过将"帮助>安装新软件..."完成后,设定这个网址为m2e和该URL的m2e-wtp,然后在安装所有建议的软件(不要忘了在那之后重新启动Eclipse的).
  • 在Eclipse中正确设置服务器:在"服务器"视图中,右键单击并选择"新建>服务器",然后按照特定服务器的步骤操作; 最后,您需要war通过"添加和删除..."屏幕添加您的内容.
  • 通过选择它并转到"Project> Clean"来清理Eclipse中的项目.
  • 右键单击Eclipse中的项目并转到"Maven> Update Project ..."来更新Maven项目.
  • 通过右键单击服务器并选择"清理"来清理服务器(这取决于您的服务器,但通常是"清除"选项).

我建议您在全新的Eclipse安装上执行所有这些步骤,以避免一般的缓存问题.

作为旁注,您的POM存在以下几个问题:

  • javax.servlet:javax.servlet-api依赖项需要具有provided范围,因为此依赖项始终由Web服务器在运行时提供.
  • javax.servlet:jstl依赖可能不需要具有compile范围并且runtime就足够了.
  • 当您不需要时,您将声明许多Spring依赖项:它们仍将被包含,因为它们已经是其他工件的传递依赖项.因此,你可以删除的声明spring-aop,spring-beans,spring-context,spring-expression,spring-tx和spring-web.
  • 您的测试依赖项缺少test范围(testng,mockito-all...)
  • <inherited>true</inherited>在您的maven-compiler-plugin声明中是不必要的,因为这是默认值.

最终的POM将是:

您可能想要解决的另一个问题是您的groupId并且artifactId不遵循Maven惯例:更喜欢使用-分隔符而不是..

  • 这是我不想听到的众所周知的答案，但它确实有效。 (2认同)
  • 已经完成了这个答案的所有建议（甚至是基本的）。使用最新的插件版本（Neon 版本）。我们不明白为什么 Eclipse 不部署与 Maven 相同的构建。它在笑......我什至在`WEB-INF/classes`中部署了资源和类测试。其他人有修复部署程序集错误的想法？谢谢你 (2认同)
  • 这显然是问题......对某些人来说,它有效,有些则不然.我有一个经典的安装与所有m2e插件和m2e-wtp(全部更新).Eclipse制作自己的配置/执行变得非常痛苦. (2认同)
