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。


当前回答

对于mac

我删除了所有旧的maven失败的下载,在我的mac上也有几个版本的maven

寻找~ /。M2 -name "*。lastUpdated" -exec grep -q " cannot transfer" {};-print -exec rm {};

之后,我简单地更新了我的eclipse

帮助->检查更新

这个问题为我解决了

这个问题的主要原因是失败的旧更新不允许你下载原型,所以如果你试图在maven的任何原型中构建项目,它会失败

其他回答

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>

这件事也发生在我身上,对此你可能有两种解决办法

If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C:\Users\Mohit.Singh.m2\repository folder and then you have to run mvn eclipse:eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --> GO to maven --> Click on update project a window will appear check the force snapshot download option and hit on OK

请确保。m2文件夹中的settings.XML文件是有效的 然后在cmd中使用以下命令清理存储库

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

创建一个文件delete_lastUpdated_and_remote.sh(使用\n):

#!/bin/bash
find $(cd $(dirname $0); pwd) -name "*.lastUpdated" -type f -print -exec rm -rf {} \;
find $(cd $(dirname $0); pwd) -name "_remote.repositories" -type f -print -exec rm -rf {} \;

把它放在本地Maven repo中,例如%userprofile%\。M2 \repository或~/。M2 /repository,并运行它。

在windows中,你也应该安装Git来运行sh文件。

我也用在jenkins的工作上。

当我在防火墙后面时,它发生在我身上。在Eclipse IDE中运行时,有时不会下载依赖项。确保使用mvn clean install -U来解决这个问题。在此之后,您将看到依赖项下载。
