I am using IntelliJ IDEA, and I have try to install the dependencies by maven but it gave me these error:

Cannot resolve plugin org.apache.maven.plugins:maven-clean-plugin:3.0.0
Cannot resolve plugin org.apache.maven.plugins:maven-resources-plugin:3.0.1
Cannot resolve plugin org.apache.maven.plugins:maven-jar-plugin:3.0.2
Cannot resolve plugin org.apache.maven.plugins:maven-compiler-plugin:3.7.0
Cannot resolve plugin org.apache.maven.plugins:maven-surefire-plugin:2.20.1
Cannot resolve plugin org.apache.maven.plugins:maven-site-plugin:3.6

I have search about similar question but they all refer to proxy problem but,

I can reach these plugin by browser without proxy and i also try to configure proxy in IntelliJ IDEA but its not working too.

Log file :

error in the image

after compiling and building it successfully by intellij and by bash still two error exist 

Cannot resolve plugin org.apache.maven.plugins:maven-clean-plugin:3.0.0
Cannot resolve plugin org.apache.maven.plugins:maven-site-plugin:3.6

what dose that mean and how to fix the remaining error in reading dependencies ?

  • See stackoverflow.com/a/42427510/104891. What errors do you see in idea.log? Did you configure the proxy for Maven per maven.apache.org/guides/mini/guide-proxies.html ? Commented Aug 28, 2019 at 20:45
  • i have update the question with lg file and i will take a look to your links Commented Aug 28, 2019 at 20:53
  • Make sure you can build without errors from the command line and the proxy is set correctly for Maven. Commented Aug 28, 2019 at 20:54
  • i have configure proxy in : setting -> appearance & behavoir -> system settings -> http proxy not in setting.xml Commented Aug 28, 2019 at 20:55

    This will not affect Maven, you must configure it in settings.xml: maven.apache.org/guides/mini/guide-proxies.html. Does it build from the command line outside of IntelliJ IDEA? Commented Aug 28, 2019 at 20:56

I think you need to put your plugins inside tag <build> instead of tag <dependencies>. Something like: 

<dependencies>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
