This is solved for me when I update maven and check the option "Force update of Snapshots/Releases" in Eclipse. this clears all errors.
So right click on project -> Maven -> update project, then check the above option -> Ok.
Hope this helps you.

It seems like your Maven is unable to connect to Maven repository at http://repo1.maven.org/maven2.

If you are using proxy and can access the link with browser the same settings need to be applied to Spring Source Tool Suite (if you are running within suite) or Maven.

For Maven proxy setting create a settings.xml in the .m2 directory with following details

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
 http://maven.apache.org/xsd/settings-1.0.0.xsd">
 <proxies>
 <proxy>
 <active>true</active>
 <protocol>http</protocol>
 <host>PROXY</host>
 <port>3120</port>
 <nonProxyHosts>maven</nonProxyHosts>
 </proxy>
 </proxies>
</settings>

If you are not using proxy and can access the link with browser, remove any proxy settings described above.

For the first error you can simply clear your local repository cache to force it download from main repository rather than checking the local one.

For second error, if you are behind proxy you should configure it this way Configuring a proxy otherwise you have a network problem now.

To me the solution was just deleted the specific folder which is giving the error from ~/.m2/repository/org/hsqldb/

After deleting the hsqldb folder I have build the project and everything is fine.

What helped me were the suggestions by @carlspring (create a settings.xml to configure your http proxy):

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
 http://maven.apache.org/xsd/settings-1.0.0.xsd">

 <proxies>
 <proxy>
 <id>myproxy</id>
 <active>true</active>
 <protocol>http</protocol>
 <username>user</username> <!-- Put your username here -->
 <password>pass</password> <!-- Put your password here -->
 <host>123.45.6.78</host> <!-- Put the IP address of your proxy server here -->
 <port>80</port> <!-- Put your proxy server's port number here -->
 <nonProxyHosts>local.net|some.host.com</nonProxyHosts> <!-- Do not use this setting unless you know what you're doing. -->
 </proxy> 
 </proxies> 
</settings>

AND then refreshing eclipse project maven as suggested by @Peter T :

"Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.

It seems me there was a network issue. On your side, or on Maven side, or anywhere in the middle. Just try again later.

If the error is permanent, check your network settings. If you are behind a proxy, you need the following in you ~/.m2/settings.xml:

<proxies>
 <proxy>
 <id>optional</id>
 <active>true</active>
 <protocol>http</protocol>
 <username>proxyuser</username>
 <password>proxypass</password>
 <host>proxy.host.net</host>
 <port>80</port>
 <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
 </proxy>
</proxies>

I strongly recommend to use a Maven Repository Manager such as Nexus. It will help you to get stable and reproducible builds with Maven. As the Repository Manager is usually in your LAN, you don't have to configure the proxy settings, but you need to define some other configurations:

I started using maven on my machine first time in while. Got this error: Could not transfer artifact from/to central (https://repo.maven.apache.org/maven2) No such file or directory
Cleaned up ~/.m2/repository directory. Don't experience this problem again

If you are in windows os and dont need any proxy
then delete the whole proxy setting

<proxies>
 <proxy>
 ..................
 </proxy> 
 </proxies> 

and replace with

<proxies/> 

and then do a maven clean build

If none of the above works then try and go this question and answer:
Maven error "Failure to transfer..."

and delete your .lastUpdated files.

1. Update Maven Project and check the option "Force update of Snapshots/Releases", it will remove errors.


2. If not, Maven clean and install the Project.


3. Still the error isn't removed, repeat step 1.

It worked for me :)

We have the Proxy set on company level.

After disabling proxy in Internet Explorer this issue was solved (looks like it is then disabled on 'system' level), so all other browsers will pick this change too.

Now I can issue MVN commands from CMD prompt and I have no problem while e.g.

"Downloading: https://repo.maven.apache.org/maven2/org/apache/maven/archetypes/maven-archetype-webapp/1.0/maven-archetype-webapp-1.0.pom"

...that was causing 'Build failure'

Disabling proxy in IE needs to be done on daily basis in our case, because on each system start it gets set

This problem was solved by following steps -

1. Go to the local m2 repository and find the directory
   org/apache/maven/plugins/maven-surefire-plugin.


2. Delete the problematic version.


3. maven update the project, then download it again.

If you are not behind any proxy and still getting connection timeout error, please check firewall settings/ antivirus. Sometimes firewall may block the connectivity from any tool (like Eclipse/STS etc..)
