Question

如果我在Eclipse中运行我的项目一切正常。但是当我这样做时：

mvn clean 
mvn package

然后开始我的项目然后它不起作用。我发现了这个区别：

蚀：

INFO  org.eclipse.jetty.server.Server:doStart:327 ~ jetty-9.2.13.v20150730

mvn package：

INFO  org.eclipse.jetty.server.Server:doStart:327 ~ jetty-9.2.z-SNAPSHOT

为什么呢？我能做什么，mvn package加载相同的码头版本9.2.13？

更新

我发现了一些额外的差异：

在Eclipse中编译（WebApplicationInitializer）：

org.eclipse.jetty.server.Server:doStart:327 ~ jetty-9.2.13.v20150730
org.eclipse.jetty.server.handler.ContextHandler$Context:log:2052 ~ No Spring WebApplicationInitializer types detected on classpath

使用mvn package（ServletContainerInitializers）进行编译：

org.eclipse.jetty.server.Server:doStart:327 ~ jetty-9.2.z-SNAPSHOT
org.eclipse.jetty.annotations.AnnotationConfiguration:configure:456 ~ ServletContainerInitializers: detected. Class hierarchy: empty

为什么mvn不使用WebApplication？

Answer 1

我怀疑你的.classpath引用了硬编码的依赖版本，而不是从pom.xml动态获取它们。这是在eclipse中修复maven项目配置的可靠方法。

右键点击项目=＆gt;配置=＆gt;转换为Maven项目（可能不需要此步骤）
删除<projectRoot>/.classpath
如果你做了2.日食（例如windows explorer），右击项目=＆gt; “刷新”
右键点击项目=＆gt; Maven =＆gt;更新项目
应创建一个没有硬编码依赖项的新.classpath

Answer 2

尝试规范，

mvn clean
mvn generate-sources
mvn install

我和＃34;包＆＃34;有问题。过去的目标。

Answer 3

Eclipse以不同于maven的方式运行项目，它将所有项目类编译为一个文件夹（即构建或目标），并将其作为java进程执行，其中包含到该构建文件夹的类路径和来自依赖项的jar。

你的maven配置解压缩所有依赖项并将它们的类放入result.jar。 mixin这个类会产生不可预测的结果，这就是为什么jetty打印出错误的版本，因为包层次结构被打破了。

package org.eclipse.jetty.util;

public class Jetty {
  public static final String VERSION;

  private Jetty() {
  }

  static {
    Package pkg = Jetty.class.getPackage();
    if(pkg != null && "Eclipse.org - Jetty".equals(pkg.getImplementationVendor()) && pkg.getImplementationVersion() != null) {
      VERSION = pkg.getImplementationVersion();
    } else {
      VERSION = System.getProperty("jetty.version", "9.2.z-SNAPSHOT");
    }

  }
}

mvn包加载其他库作为Eclipse
