Eclipse插件无法处理Maven工具链插件

Question

当我在我的pom.xml中有Maven工具链插件时：

Cannot find matching toolchain definitions for the following toolchain types:
jdk [ vendor='oracle' version='1.8' ]
Please make sure you define the required toolchains in your ~/.m2/toolchains.xml file. (org.apache.maven.plugins:maven-toolchains-plugin:1.1:toolchain:default:validate)

org.apache.maven.plugin.MojoFailureException: Cannot find matching toolchain definitions for the following toolchain types:
jdk [ vendor='oracle' version='1.8' ]
Please make sure you define the required toolchains in your ~/.m2/toolchains.xml file.

我在“c：\ user \ name \ .m2”文件夹中有“toolchains.xml”，其中包含Orcale 1.8 JDK的定义，Maven在命令行中工作正常，但Eclipse（Neon和Oxygen）报告以下内容错误：

<plugin>
    <groupId>org.eclipse.m2e</groupId>
    <artifactId>lifecycle-mapping</artifactId>
    <version>${m2e.lifecycle-mapping.version}</version>
    <configuration>
        <lifecycleMappingMetadata>
            <pluginExecutions>
                <pluginExecution>
                    <pluginExecutionFilter>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-toolchains-plugin</artifactId>
                        <versionRange>[0.0.0,)</versionRange>
                        <goals>
                            <goal>toolchain</goal>
                        </goals>
                    </pluginExecutionFilter>
                    <action>
                        <ignore/> <!-- Changed from execute to ignore -->
                    </action>
                </pluginExecution>
            </pluginExecutions>
        </lifecycleMappingMetadata>
    </configuration>
</plugin>

编辑：我发现奇怪的事情，如果我将生命周期映射中的“操作”从“执行”更改为“忽略”，那么错误将从Eclipse中消失：

jQuery('.custom_field_name').keyup(function () { 
           var v = this.value.replace(' ','_');
           var vee = v.toLowerCase().replace(/\W/,'');
           if (vee!=this.value) this.value = vee;
});

但是，这不仅仅意味着Eclipse / m2e现在忽略了工具链吗？是否还需要其他一些配置/更改才能使其正常工作？
