Question

我在尝试构建maven项目时在我的pom.xml中收到错误。这个插件出现错误：

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>

这是Eclipse显示的错误：

Multiple annotations found at this line:
- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:
 2.3.2:compile (execution: default-compile, phase: compile)
- CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: 
 PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not 
 be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2 (): 
 ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.maven:maven-toolchain:jar:1.0: 
 ArtifactResolutionException: Failure to transfer org.apache.maven:maven-toolchain:pom:1.0 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-toolchain:pom:1.0 from/to central (http://
 repo.maven.apache.org/maven2): The operation was cancelled.

Answer 1

似乎解决方案失败了。

使用-U标志运行mvn以忽略缓存并重新尝试解析

（alt + f5对话框也可能有帮助）

Answer 2

当我遇到这个问题时，我发现这是由于之前的网络问题。本地Maven存储库避免立即重新尝试。解决此问题的最佳方法是使用eclipse“更新Maven项目”（ALT + F5）功能结束检查“强制更新快照/版本”选项。

Answer 3

这对我不起作用，将maven编译器版本更改为2.5.1终于为我工作了，希望这可以帮助那些仍在努力解决这种依赖性的人

<build>
     <pluginManagement>
        <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>2.5.1</version>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                    </configuration>
                </plugin>
        </plugins>
        </pluginManagement>
    </build>

Answer 4

按（ALT + F5）更新Maven项目，然后选择“强制更新快照/版本”选项。也适合我

Answer 5

有类似的问题。 Maven更新和强制更新快照对我不起作用。

已按照以下步骤操作，问题已解决：

在eclipse中删除项目。
删除.Project文件和。设置文件夹。
再次将项目导入为现有的maven项目。
