'Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved
I have install maven in my machine. I have properly set the class-path and maven home folder. Every time I execute mvn clean install, it gives me exception. I have also tried to delete the .m2 folder but the same result.
mvn -version output

Solution 1:[1]
Your debug output indicates that Clean is the first thing that it's trying to run, so I'm guessing it's failing to download any plugins from central.
First off, see if you can download the plugin jar directly in a web browser: http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.jar
If that works then your web browser has connectivity to central but maven doesn't. That suggests to me that your web browser is using a proxy that maven isn't configured to use.
Maven proxy settings are described in depth here. To simplify that a little fill this out (replace the protocol/host/port with the values from your internet settings) and put it in the <settings> tag of your maven settings.xml file:
<proxies>
<proxy>
<id>proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>proxy.example.com</host>
<port>8080</port>
</proxy>
</proxies>
Solution 2:[2]
The error is due to maven official repository being not accessible. This repo (https://repo.maven.apache.org/maven2/) is not accessible so follow these steps:
- Firstly delete your /home/user/.m2 folder
- create .m2 folder at user home and repository folder within .m2
- copy the default settings.xml to .m2 folder
- Change mirrors as follows in the settings.xml as shown in below snap mirror_settings
<mirrors>
<mirror>
<id>UK</id>
<name>UK Central</name>
<url>http://uk.maven.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>- Execute the mvn clean commands now .....
Solution 3:[3]
In my case my problem was that I was using an older version of NetBeans. The Maven repository removed an http reference, but the embedded Maven in Netbeans had that http reference hard-coded. I was really confused at first because my pom.xml referenced the proper https://repo.maven.apache.org/maven2.
Fixing it was pretty simple. I downloaded the latest zip archive of Maven from the following location and extracted it to my machine: https://maven.apache.org/download.cgi
Within Netbeans at Tools -> Options -> Java -> Maven on the "Execution" section I set "Maven Home" to the newly extracted zip file location.
Now I could build my project....
Solution 4:[4]
It might be that you are forgetting to specify the settings which was the case with me.
Try:
mvn clean install -s settings_file.xml
Solution 5:[5]
I faced the same problem but it resolved with some changes in setting.xml(.*\apache-maven-3.3.3\apache-maven-3.3.3\conf).
<proxies>
<proxy>
<id>proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>HOSTNAME</host>
<port>PORT</port>
</proxy>
</proxies>
Just check the hostname and port from the IE setting -> connections -> LAN Setting -> Proxy server
Hope this will resolve your problem also :)
Solution 6:[6]
I faced the same problem, even if I was working on my home wifi connection, without any proxy requirements.
My project was created at c:\users\<>\Workspace\Project\
When I went to above location and ran
mvn clean install
I got below error:
[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its de
endencies could not be resolved: Failed to read artifact descriptor for org.apa
he.maven.plugins:maven-clean-plugin:jar:2.5: Could not transfer artifact org.ap
che.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.mave
.apache.org/maven2)
It took me entire day to try ways and means to crack this, but the solution in my case, was damn simple.
I moved my project to non-user specific location, at E:\Workspace\Project\
This has done wonders for me!
Solution 7:[7]
I resolved this issue by switching to the oracle jdk from open jdk 8.
$ java -version java version "1.8.0_221" Java(TM) SE Runtime Environment (build 1.8.0_221-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
Solution 8:[8]
This is what worked for me in IntelliJIdea:
Go to File -> Build, Execution, Deployment -> Build Tools -> Maven -> Repositories
Check that there are two repositories:
https://repo.maven.apache.org/maven2 (Remote)
C:/Users/_user_/.m2/repository (Local)
And then click on Update for both repos. The update of remote repository will take a while, but in the end click on OK and that's all.
Solution 9:[9]
I faced the same problem and was frustrated to see as to all options i tried and none of them work,
Turns out once you have configured everything correctly including settings.xml
just clear your local repository folder and try mvn commands. That greatly helped me
Hope this helps others
Solution 10:[10]
I faced a similar issue. Try to follow the below steps: Manually delete the .m2 folder. Refer to the settings.xml file and check if the repository details are proper, like id and url tags. Also make sure you are connected to same network and check if the URL is accessible from browser. And lastly keep maven projects in /home/User/.
Solution 11:[11]
refering to Deepak Vishwakarma's answer, I tried with that and was facing same problem with the url-problem. I installed maven-3.6.3 and inside .m2 folder I found a
settings.xml.bak
file and from that copied that mirror link and just changed url what @Deepak did. It worked like charm! Mirror link I got from that .bak file
http://local.maven.repo:9081/nexus/content/groups/public
Then executed :
mvn clean
mvn clean install
Solution 12:[12]
I have faced the same issue. I have changed the maven-assembly-plugin to 3.1.1 from 2.5.3 in POM.xml
Proposed version should be done under plugin section. enter code here artifact Id for maven-assembly-plugin
Solution 13:[13]
Just deleting repository folder in .m2 folder resolved the same issue.
Solution 14:[14]
Think to change JDK used in your project. For me I changed JDK from 1.6 to 1.8 and I updated maven.
Solution 15:[15]
For all the Windows users, try moving your codebase to a shorter windows path for eg: C:/myProj
Deeply nested Maven jar files can create a longer file path in windows. Since windows OS, by default, limits the file path length to 260 characters, it throws exception when trying to read a file located at a path that becomes more than 260 characters.
You can change this default to increase this limit to more than 260 chracters. Search around the web and you will find many posts on how to do that.
You can face similar problem while using npm packages also.
Solution 16:[16]
I faced the same issue but, in my case, I had only to point my project to a JDK instead of the JRE in the build path then it solved the issue and I was able to import all maven dependencies with no problem!
Solution 17:[17]
None of the other answers worked for me. The solution that worked for me was to download the missing artifact manually via cmd:
mvn dependency:get -DrepoUrl=http://repo.maven.apache.org/maven2/ -Dartifact=ro.isdc.wro4j:wro4j-maven-plugin:1.8.0
Solution 18:[18]
After creating the sample app from spring initializr, I got the same type of error Cannot resolve plugin org.apache.maven.plugins:maven-install-plugin:2.5.2 after running the application from my IntellijIdea.
In my project directory I opened the folder mvnw from intellijIdea
It was displaying the option for install on top of this file
I clicked on install
After successful installation, I ran the spring application once again, It ran without giving any error.
Solution 19:[19]
- Locate settings.xml under conf folder in Maven folder.
- Locate proxies tag, add the following.
<proxies>
<proxy>
<id>proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>your company host</host>
<port>your company port</port>
</proxy>
</proxies>
Solution 20:[20]
The problem is probably that the JVM client doesn't trust the repo.maven.apache.org certificate. As suggested, you can try and access https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom in your browser.
If that works - this is probably the case. You will have to explicitly tell the JMV to trust maven certificate. You can refer to the answer here "PKIX path building failed" and "unable to find valid certification path to requested target"
for me on Mac OS, the certificate file is located at /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/jre/lib/security and the certificate you need is the one presented to your browser when you enter the URL mentioned above
