我试图使用Maven (m2eclipse)建立一个项目,但我在Eclipse中得到这个错误:

Description Resource Path Location Type Could not calculate build plan: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from http://repo1.maven.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.plugins:maven-compiler-plugin:pom:2.0.2 from/to central (http://repo1.maven.org/maven2): No response received after 60000 ExampleProject Unknown Maven Problem

什么好主意吗? 如果你能告诉我如何检查是否一切配置正常,那就太有帮助了。

如果你是一个代理,你必须更新settings.xml文件(在你的MAVEN_HOME的conf文件夹下,文件本身包含关于代理设置的信息),另外你可能需要更新你的Eclipse网络设置(窗口->Preferences…)—>类型Network Connections)。

尝试使用-X或——debug来获得调试输出,这可以提供关于问题的额外信息。

这在Windows中也适用。

Locate the {user}/.m2/repository (Using Juno /Win7 here) In the Search field in upper right of window, type ".lastupdated". Windows will look through all subfolders for these files in the directory. (I did not look through cache.) Remove them by Right-click > Delete (I kept all of the lastupdated.properties). Then go back into Eclipse, Right-click on the project and select Maven > Update Project. I selected to "Force Update of Snapshots/Releases". Click Ok and the dependencies finally resolved correctly.

删除所有失败的下载:

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

windows:

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i

然后在eclipse中右键单击您的项目,选择Maven->“更新项目…”,确保在结果对话框中选中“更新依赖项”,然后单击确定。

删除存储库中的所有文件。

转到c:\ users \ dell。M2 \资源库,选择所有文件并删除它。

然后转到项目,右键单击maven更新项目(Alt+F5)。它将下载存储库中的所有依赖文件。

对我来说,我只是在POM.xml文件中添加了下面的xml代码。在我右键单击项目-> Maven ->更新项目后,我检查了快照/发布的强制更新**,一切正常

    <dependencies>
        <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/javax.servlet.jsp/jsp-api -->
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.1</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/jstl/jstl -->
        <dependency>
            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

只需删除maven本地存储库中的原型。如上所述,它发生在原型下载失败的情况下。
