How to set NetBeans 7 internet connection?

Question

I am using NetBeans 7. Tried to create a Maven Java project, failed.

In NetBeans

mvn.bat -DarchetypeVersion=1.1 -Darchetype.interactive=false -DgroupId=com.mycompany -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeRepository=http://repo1.maven.org/maven2/ -Dversion=1.0-SNAPSHOT -DarchetypeGroupId=org.apache.maven.archetypes -Dbasedir=F:\\NetBeansProjects -Dpackage=com.mycompany.mavenproject1 -DartifactId=mavenproject1 "-Dmaven.repo.local=C:\\Documents and Settings\\xxx\\.m2" --batch-mode archetype:generate

It failed, because

Could not transfer metadata org.codehaus.mojo/maven-metadata.xml from/to central (http://repo1.maven.org/maven2): Error transferring file: Connection timed out: connect

Then copy that command into DOS, it works.

Looks like NetBeans can't connect to internet. Eclipse on the same machine can connect to remote internet.

Answer 1

The issue is that NetBeans 7 comes bundled with an embedded version of Maven. This means that any proxy settings you may have configured under your downloaded Maven distribution are not used by NetBeans.

You have two options:

• Tools > Options > Miscellaneous > Maven > Maven Home -- point NetBeans to your existing Maven download; that is, where you have configrued settings.xml with your proxy settings;

• Edit path/to/nb7/java/maven/conf/settings.xml with your proxy settings.

Answer 2

Well it is not necessarily internet issue

• If you are behind proxies you need to tell maven in settings.xml about proxy
• If that lib ins't available on the maven repos download it from official sitre and install it manually
