Question

我收到错误，因为我错误地错误地放置了依赖项标记之外的依赖项。我纠正了它，清理，更新，构建，但我仍然有错误。我的POM有什么问题？

我得到的错误是：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'dependency'. One of '{"http://maven.apache.org/POM/4.0.0":parent, "http://maven.apache.org/POM/4.0.0":description, "http://maven.apache.org/POM/4.0.0":prerequisites, "http://maven.apache.org/POM/4.0.0":issueManagement, "http://maven.apache.org/POM/4.0.0":ciManagement, "http://maven.apache.org/POM/4.0.0":inceptionYear, "http://maven.apache.org/POM/4.0.0":mailingLists, "http://maven.apache.org/POM/4.0.0":developers, "http://maven.apache.org/POM/4.0.0":contributors, "http://maven.apache.org/POM/4.0.0":licenses, "http://maven.apache.org/POM/4.0.0":scm, "http://maven.apache.org/POM/4.0.0":organization, "http://maven.apache.org/POM/4.0.0":build, "http://maven.apache.org/POM/4.0.0":profiles, "http://maven.apache.org/POM/4.0.0":modules, "http://maven.apache.org/POM/4.0.0":repositories, "http://maven.apache.org/POM/4.0.0":pluginRepositories, "http://maven.apache.org/POM/4.0.0":reports, "http://maven.apache.org/POM/4.0.0":reporting, "http://maven.apache.org/POM/4.0.0":dependencyManagement, "http://maven.apache.org/POM/4.0.0":distributionManagement}' is expected.

Answer 1

<dependency>
<groupId>it.polimi.ingsw</groupId>
<artifactId>cg_43</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging> replace with   <type>jar</type>
    </dependency>

Answer 2

删除项目并再次导入它会使错误消失。

即使在清理项目并在XML中验证之后，Eclipse也会在此POM中发出错误信号
