插件org.apache.maven。插件:maven-compiler- compiler-plugin或其依赖项之一无法解决

I'm having some issues to configure properly my eclipse to work with maven.

我有一些问题需要正确配置我的eclipse，以便与maven一起工作。

I create a new project, this one is correctly build with maven in command line (mvn install), but in Eclipse I got this error:

我创建了一个新项目，这个项目是用maven在命令行(mvn安装)中正确构建的，但是在Eclipse中我得到了这个错误:

CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 (): ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.maven:maven-settings:jar:2.2.1: ArtifactResolutionException: Failure to transfer org.apache.maven:maven-settings:pom:2.2.1 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 org.apache.maven:maven-settings:pom:2.2.1 from/to central : NullPointerException pom.xml /test line 9 Maven Project Build Lifecycle Mapping Problem

CoreException:无法获取用于插件执行default-compile的参数编译器的值:PluginResolutionException: plugin .apache -compile -plugin:3.1或它的一个依赖项无法解决:未能收集到对org.apache.maven.plugins的依赖项:maven-compile -plugin:jar:3.1 (): ArtifactDescriptorException:未能读取org.apache.maven的构件描述符:maven-settings:jar:2.2.1: ArtifactResolutionException:未能从http://repo.maven.apache.maven .maven:maven-settings:pom:2.2.1从http://repo.maven.apache.org/maven2缓存在本地存储库中，直到central的更新间隔被强制或更新，才会重新尝试解析。原始错误:无法传输工件组织。apache.maven:maven-settings:pom:2.2.1 from/to central: NullPointerException pom。xml /测试行9 Maven项目构建生命周期映射问题。

Here is my settings.xml conf :

这是我的设置。xml配置:

<proxy>
  <active>true</active>
  <protocol>http</protocol>
  <username>myuser</username>
  <password>$mymdp</password>
  <host>myhost</host>
  <port>8080</port>
  <nonProxyHosts>some.host.com</nonProxyHosts>
</proxy>
....

<repository>
     <id>central</id>
     <name>central repo m2</name>
     <url>http://central.maven.org/maven2</url>
</repository>

I choose the correct maven installation (in Preference -> Maven -> Install)

我选择正确的maven安装(首选-> maven ->安装)

I also direct my user settings on the correct settings.xml (Preferences -> Maven -> User Settings)

我还将用户设置指向正确的设置。xml(首选项-> Maven ->用户设置)

But I still got this error in Eclipse and everything goes well with maven command line. Do you have and idea?

但是我在Eclipse中仍然有这个错误，并且maven命令行运行得很好。你有什么想法吗?

Have you tried to remove the proxy username and password? A similar poster encountered that issue:

您是否试图删除代理用户名和密码?类似的海报也遇到了这个问题:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

无法计算构建计划:插件org.apache. mavenins:maven-jar-plugin:2.3.2或其中一个依赖项无法解决

Failing that I found the following worked:

如果没有，我发现以下方法是有效的:

Delete project in Eclipse (but do not delete the contents on disk)
在Eclipse中删除项目(但不删除磁盘上的内容)
Delete all files in your Maven repository
删除Maven存储库中的所有文件
Re-download all Maven dependencies:
重新下载所有Maven的依赖关系:

mvn dependency:resolve

mvn依赖性:解决

Start up Eclipse
启动Eclipse
Ensure that Eclipse is configured to use your external Maven installation (Window->Preferences->Maven->Installations)
确保将Eclipse配置为使用外部Maven安装(窗口->首选项->Maven->安装)
Re-import the existing project(s) into Eclipse
将现有项目重新导入Eclipse。
Ensure that there are no Maven Eclipse plugin errors on the final screen of the project import
确保在项目导入的最终屏幕上没有Maven Eclipse插件错误。

You only need to delete one folder it is throwing error for. Just go to your M2 repo and org/apache/maven/plugins/maven-compiler-plugins and delete the folder 2.3.2

您只需要删除它正在抛出错误的一个文件夹。只需进入M2 repo和org/apache/maven/plugins/maven-compiler-plugins并删除2.3.2文件夹

The issue has been resolved while installation of the maven settings is provided as External in Eclipse. The navigation settings are Window --> Preferences --> Installations. Select the External as installation Type, provide the Installation home and name and click on Finish. Finally select this as default installations.

当maven设置的安装作为Eclipse中的外部设置提供时，这个问题已经解决。导航设置是窗口——>首选项——>安装。选择外部作为安装类型，提供安装home和名称，然后单击Finish。最后选择这个作为默认安装。

I was getting this problem when using IBM RSA 9.6.1 when building a brand new development machine. The problem for me ended up being because of HTTPS on the Global Maven repository. My solution was to create a Maven settings.xml that forced it to use HTTP.

当使用IBM RSA 9.6.1构建一个全新的开发机器时，我遇到了这个问题。我的问题最终是由于在全局Maven存储库上的HTTPS。我的解决方案是创建Maven设置。迫使它使用HTTP的xml。

The key to me was that the central repository was empty when I exploded it under Maven Repositories -- > Global Repositories

我的关键是，当我在Maven存储库(>全局存储库)下爆炸时，*存储库是空的

Using the following settings file worked for me:

使用以下设置文件对我有用:

<settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>insecurecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>insecurecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>

I got the idea from this * question.

我是从这个*的问题中得到这个想法的。
