Question

我正在关注Hibernate documentation并试图在我的日食中创建一个Maven项目。我已经根据Hibernate文档中显示的groupId, artifactId and version中的信息，选择了eclipse中显示的默认选项，除了我选择的org.hibernate.tutorials, hibernate-tutorial, 1.0.0-SNAPSHOT详细信息（pom.xml之外），我创建了一个新的maven项目。之后，我用文档中显示的文件替换了项目中的pom.xml文件。然后我添加了文档中缺少的每个依赖项的版本详细信息。这是我的最终pom.xml文件：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>org.hibernate.tutorials</groupId>
<artifactId>hibernate-tutorial</artifactId>
<version>1.0.0-SNAPSHOT</version>
<name>First Hibernate Tutorial</name>

<build>
     <!-- we dont want the version to be part of the generated war file name -->
     <finalName>${artifactId}</finalName>
</build>

<dependencies>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.6.Final</version>
    </dependency>

    <!-- Because this is a web app, we also have a dependency on the servlet api. -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>

    <!-- Hibernate uses slf4j for logging, for our purposes here use the simple backend -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>1.5.6</version>
    </dependency>

    <dependency>
        <groupId>javassist</groupId>
        <artifactId>javassist</artifactId>
        <version>3.12.1.GA</version>
    </dependency>
</dependencies>

现在在eclipse中我看到以下错误：

1) Maven Configuration Problem:

Failure to transfer
org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from
http://repo.maven.apache.org/maven2 was cached in the local
repository, resolution will not be reattempted until the update
interval of central has elapsed or updates are forced. Original error:
Could not transfer artifact

cancelled.

2) Maven Problems:

4) Maven Problem:

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution: default-compile, phase: compile)

5) Maven Problem:

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (execution: default-testCompile, phase: test-compile)

6) Maven Problem:

Project configuration is not up-to-date with pom.xml. Run Maven->Update Project or use Quick Fix.

更新：当我在eclipse中构建项目时，我收到以下错误：

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'hibernate-tutorial'.
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5

请帮助我如何解决这些问题。我在学习Hibernate的第一步就被阻止了。

提前致谢。

Answer 1

退出日食

删除（或重命名为安全）您的.m2 / repository目录，它将位于您计算机上的home directory。

启动eclipse，右键单击您的项目，选择Update Maven Project，选中Force Update of Snapshots / Releases，按OK

Answer 2

它不允许我重命名.m2目录。以下是解决我的错误的详细步骤： *我从Eclipse中删除了项目 *退出Eclipse *从C / Users / Kshitija /位置删除（未移位删除）.m2文件夹 *打开Eclipse，再次创建maven项目 *右键点击项目 - ＆gt; Maven - ＆gt;更新项目 - ＆gt;选择＆＃34;选中强制更新快照/版本＆＃34;，然后按确定一旦项目建成，错误就消失了
