Maven Unable to Collect Dependencies at Extra Repositories - java

I working on converting a project from ant to maven and am getting errors trying to pull in jars from geomajas.
I am not behind a firewall and the dependencies from maven central are downloading. I have also added geomajas to the repositories in my projects pom.xml.
Below are the relevant portions from the pom.xml and the error I am getting.
If I instead define the jar dependency with a system path to a local copy of the jar the project builds successfully.
<dependency>
<groupId>org.lobobrowser</groupId>
<artifactId>cobra</artifactId>
<version>0.98.4</version>
</dependency>
.....
<repository>
<id>geomajas</id>
<name>Geomajas Maven Repository</name>
<url>https://maven.geomajas.org/(https://maven.geomajas.org/)</url>
</repository>
[ERROR] Failed to execute goal on project niksun-services-util: Could not resolve dependencies for project com.niksun:niksun-services-util:jar:main: Failed to collect dependencies at org.lobobrowser:cobra:jar:0.98.4: Failed to read artifact descriptor for org.lobobrowser:cobra:jar:0.98.4: Could not transfer artifact org.lobobrowser:cobra:pom:0.98.4 from/to geomajas (http://maven.geomajas.org/(http://maven.geomajas.org/)): connect timed out -> [Help 1]

Maven dependency version

When doing a mvn clean install -U I am getting:
[ERROR] Failed to execute goal on project xxx-security: Could not resolve dependencies for project xxx:xxx-security:jar:50-SNAPSHOT: Failed to collect dependencies at

dard/org/mybatis/mybatis/$%7Bmybatis.version%7D/mybatis-$%7Bmybatis.version%7D.pom. Return code is: 400 , ReasonPhrase:Invalid repository path. -> [Help 1]
What I don't get is why maven is using mybatis.version in the url to get the dependency rather than a version number. I have searched the code and cannot find mybatis.version in there. I did find:
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.0.4</version>
</dependency>
So why is maven using mybatis.version rather than 3.0.4?
It looks like your xxx:xxx-persistence:jar:50-SNAPSHOT jar has internal dependency with org.mybatis:mybatis:jar:${mybatis.version}. Provided that you define mybatis.version in your properties.
You can do following:
Execute mvn dependency:tree to check which specific jar has this dependency.
Also define <mybatis.version>3.0.4</mybatis.version> under <properties> section of pom.xml. You can optionally remove <version>3.0.4</version> from your <dependency> section where you defined mybatis dependency.

Maven failed to download dependencies after adding dependency to pom.xml

What is the correct way to add dependency in Intelli?
I have added
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
to pom.xml but I got the error

when I do mvn install. I have try maven->reload project and it still didn't work. Any idea on how to solve the problem?
After a failed attempt, maven will leave a small file in your local .m2 repository that will prevent any attempt to re-download the file unless the update interval has elapsed or you force the updates using the maven -U switch described in other answers.
Just delete the folder for that artifact in your local m2 repository and update you project; a new download attempt will trigger.
rm -rf ~/.m2

Unable to connect to Maven Central Repository within organization due to Firewall, Maven does not connect to internal URL and fails in simple project

I am working inside an organization and the firewall settings donot allow download of jars from Maven Central repository. Instead the organization has created an internal repository https://internalurl that exactly mirrors the directory or package structure of the Maven central repository
So In my $HOME.m2\settings.xml I have put the following entries so that the internalurl is used by Maven build instead of Maven Central repository
<settings xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0">
<mirrors>
<mirror>
<id>central-proxy</id>
<name>Local proxy of central repo</name>
<url>https://internalurl</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
</settings>
Next I am trying to create a simple "Maven Web Project" on Eclipse by selecting Archetype "maven-archetype-webapp" version 1.0 from GroupId org.apache.maven.archetypes
But once I enter the Project GroupId, ArtifactId and click Finish I get the following error
could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:1.0 from any of the configured repositories
Could not resolve artifact org.apache.maven.archetypes:maven-archetype-webapp:pom:1.0
Failure to transfer org.apache.maven.archetypes:maven-archetype-webapp:pom:1.0 from https://internalurl was cached in the local repository, resolution will not be reattempted until the update interval of central-proxy has elapsed or updates are forced. Original error: Could not transfer artifact
When I go to our internal Maven Repository site, and drill down to the below URL and the package structure, I can see that the maven-archetype-webapp:pom:1.0 is present
If I goto https://internalurl/org/apache/maven/archetypes/maven-archetype-webapp/1.0
I can see the following 2 files
maven-archetype-webapp-1.0.jar
maven-archetype-webapp-1.0.pom
So why is Eclipse reporting the ERROR and not creating the project ?
Please Help.
thanks
You must change your setting like below.
<mirror>
<id>central-proxy</id>
<name>Local proxy of central repo</name>
<url>https://internalurl</url>
<mirrorOf>*</mirrorOf>
</mirror>
According to the document below, Because <mirrorOf>central</mirrorOf> means to point to a mirror of the Maven central repository.

How can I download Infrequently used dependencies in maven?

Version: maven 3.6.3
I try to put this dependency into pom.xml,but it not auto download
<dependency>
<groupId>com.datastax.spark</groupId>
<artifactId>spark-cassandra-connector_2.11</artifactId>
<version>2.4.3</version>
</dependency>
so i use command line:
mvn dependency:get -DremoteRepositories=http://repo1.maven.org/maven2 -DgroupId=com.datastax.spark -DartifactId=spark-cassandra-connector_2.11 -Dversion=2.4.3 -Dtransitive=false
but it give me couldn't download artifact error log :
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:get (default-cli) on project standalone-pom: Couldn't download artifact: Could not transfer artifact com.datastax.spark:spark-cassandra-connector_2.11:jar:2.4.3
Do I need to upgrade remoteRepositories?
Why are some commonly used packages automatically downloaded quickly ? such as guava,commons-lang.
Some new versions are always problematic to rely on for download,Is it no cache in
repository?
How can I download the dependency? Thanks

Hudson Maven ${basedir} can't find dependency

I have a created a maven repo in a directory called lib in the base of my project.
I can use maven to build this project and fetch dependencies from the repo in the lib directory. When I try to build this project with Hudson, Hudson can not find the dependencies in the lib repo.
Here are the relevant parts of the project pom:
<dependency>
<groupId>manitou</groupId>
<artifactId>manitou.cxf.jar</artifactId>
<version>1.0.0</version>
</dependency>
</dependencies>
<repositories>
<repository>
<id>ErpClientsLibRepo</id>
<url>file://${basedir}/lib</url>
</repository>
</repositories>
Here are the errors from Maven when ran from Hudson:
[INFO] o.h.m.e.h.MavenExecutionResultHandler - Build failed with exception(s)
[INFO] o.h.m.e.h.MavenExecutionResultHandler - [1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project DigabitERPClients: Could not resolve dependencies for project com.digabit:DigabitERPClients:jar:1.2.0: Failure to find manitou:manitou.cxf.jar:jar:1.0.0 in file:///opt/eng/hudson/jobs/20-DigabitJParent/workspace/DigabitErpClients/lib was cached in the local repository, resolution will not be reattempted until the update interval of ErpClientsLibRepo has elapsed or updates are forced

Here is a dir listing at the path Maven (As ran by Hudson) seems to be looking at:
[root#vail lib]# cd /opt/eng/hudson/jobs/20-DigabitJParent/workspace/DigabitErpClients/lib
[root#vail lib]# ls
manitou
[root#vail lib]# ls manitou/
manitou.cxf.jar
[root#vail lib]#
Any ideas what I'm doing wrong? Thanks
I went into the hudson project and forced maven to update, now the build works :S
