I'm trying to build a DSpace program. I get the following exception:

INFO: I/O exception (java.net.SocketException) caught when processing request to {s}->https://repo.maven.apache.org:443: Permission denied: connect

I quote the contents of the CMD output:

Of the recommendations on the Internet, I found only the use of the Djava.net.preferIPv4Stack = true option, but it does not work in my case. It is also recommended to disable the firewall. Disconnected. Also does not work. They also say that this is a typical Java 7 error, but the Oracle website does not allow you to download Java 6, arguing that you only need to use the latest version, so I can’t confirm this version.

It turned out that this exception does not occur on the server, that is, DSpace is collected without errors. Perhaps the server works bypassing a certain firewall, but I don’t know how to check it.

  • And why not 8 download? - Andrew Bystrov
  • I have the eighth)))). I think the problem with the seventh version is relevant for the eighth. - DP0
  • And through the browser on the machine that starts the maven, you can go to this address repo.maven.apache.org:443 ? - Andrew Bystrov
  • Yes. All links are working. - DP0

    Do you work in an office, do you have a proxy? Or from home? - Igor Kudryashov

Most likely there is a proxy. If its parameters are unknown, try changing the https protocol to http. This can be done, for example, by setting a profile in your settings.xml file.

 <profiles> <profile> <id>central</id> <!--Override the repository (and pluginRepository) "central" from the Maven Super POM --> <repositories> <repository> <id>central</id> <url>http://repo1.maven.org/maven2</url> <releases> <enabled>true</enabled> </releases> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>central</id> <url>http://repo1.maven.org/maven2</url> <releases> <enabled>true</enabled> </releases> </pluginRepository> </pluginRepositories> </profile> </profiles>

Next you need to activate this profile.

 <activeProfiles> <!--make the profile active all the time --> <activeProfile>central</activeProfile> </activeProfiles>

Just in case, look at the setting of the proxy Configuring a proxy

  • I do not have the settings.xml file. There is pom.xml. Looks like yours, but there are no <repository> tags. - DP0
  • Your settings.xml file is in your OS profile in the .m2 directory. For example, for Windows 7, this would be C:\Users\ВАШЕ_ИМЯ_ПОЛЬЗОВАТЕЛЯ\.m2\settings.xml - Igor Kudryashov
  • This file is neither on my computer nor on the server. In the .m2 directory there is only a subdirectory repository - DP0
  • You should read this - Installing Apache Maven and this - Configuring Apache Maven - Igor Kudryashov
