Question

Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved: 
Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:2.5:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
                <compilerArgument>-Xlint:all</compilerArgument>
                <showWarnings>true</showWarnings>
                <showDeprecation>true</showDeprecation>
            </configuration>
        </plugin>

既得。删除.m2,maven clean,...

我需要改变什么？

Answer 1

我相信错误就像它说的那样：它不支持未加密的请求。所以我们应该把你的URL更改为HTTPS。

https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom

如果由于某种原因不能使用HTTPS,请使用：

http://insecure.repo1.maven.org/maven2/

对于Maven Repos。
