I’m having some issues to configure properly my eclipse to work with maven.
I create a new project, this one is correctly build with maven in command line (
mvn install), but in Eclipse I got this error:
CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 (): ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.maven:maven-settings:jar:2.2.1: ArtifactResolutionException: Failure to transfer org.apache.maven:maven-settings:pom:2.2.1 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven:maven-settings:pom:2.2.1 from/to central : NullPointerException pom.xml /test line 9 Maven Project Build Lifecycle Mapping Problem
Here is my settings.xml conf :
<proxy> <active>true</active> <protocol>http</protocol> <username>myuser</username> <password>$mymdp</password> <host>myhost</host> <port>8080</port> <nonProxyHosts>some.host.com</nonProxyHosts> </proxy> .... <repository> <id>central</id> <name>central repo m2</name> <url>http://central.maven.org/maven2</url> </repository>
I choose the correct maven installation (in Preference -> Maven -> Install)
I also direct my user settings on the correct settings.xml (Preferences -> Maven -> User Settings)
But I still got this error in Eclipse and everything goes well with maven command line. Do you have and idea?
Have you tried to remove the proxy username and password? A similar poster encountered that issue:
Failing that I found the following worked:
