I try to build a project by maven.I tried
$ mvn archetype:generate -DgroupId=org.thoughtworks.app -DartifactId=mvntest -DarchetypeArtifactId=maven-archetype-quickstart
It worked.And then I tried
$ mvn archetype:generate -DgroupId=org.thoughtworks.app -DartifactId=mvntest
I mean,I delete archetypeArtifactId parameter.It fail,I didn't supply it with Internet.the error message is here.Is this parameter made it need Internet?Forget about other depedency.

After you have all the dependencies downloaded on your local repository, then you can run mvn command with -o (offline) option and it should work, unless you don't need any other dependency from the remote repository (when the internet connection is needed).
If you have a repository with all the dependencies needed in your network you can reach on without the outside internet connection, just edit your settings.xml for your intranet dependencies.

I am trying to warm up my Docker + Maven cache before building a Kotlin project.
As suggested by many Maven/Docker threads, my docker file looks like this:
COPY pom.xml .
RUN mvn dependency:go-offline
COPY ./src/ src/
RUN mvn package
The thought is that if I change a file in the ./src directory, I want docker cache to skip maven's lengthy dependency download page.
My problem is that the mvn package command still downloads alot of files.
I tried to use mvn -o package (maven offline flag) to diagnose what dependencies are missing, but it just complains that it cannot download dependencies. But I would have expected that the dependencies would allready be downloaded in the previous step. Here are the errors that I get with the "-o" flag:
Step 8/13 : RUN mvn dependency:go-offline
---> Using cache
---> 0334facb9cc9
Step 9/13 : COPY ./src/ src/
---> Using cache
---> 27149a191017
Step 10/13 : RUN mvn -o package
---> Running in 5183eced32ca

Try following mvn commands, it saved me from the maven error.
RUN mvn --batch-mode --errors --strict-checksums --threads 1C \
org.apache.maven.plugins:maven-dependency-plugin:3.0.2:go-offline
RUN mvn --batch-mode --errors --offline package
From what I gathered from various sources go-offline not always handles caching packages in a correct way, leaving some of them outside of the local repository (see pull request on GitHub).
In my case, the standard mvn dependency:go-offline used go-offline 2.8 and returned errors. I then tried running mvn org.apache.maven.plugins:maven-dependency-plugin:3.2.0:go-offline but I still had some issues with different packages.
What worked for me was using a different "go-offline" plugin available at GitHub.
Using
mvn de.qaware.maven:go-offline-maven-plugin:resolve-dependencies
finally did the job.
When I try to run the mvn sonar:sonar target maven are unable to run sonar, here is the relevant part of the mvn output:
[INFO] Execute: org.codehaus.sonar:sonar-maven-plugin:3.6:sonar
[WARNING] While downloading javax.xml:jaxrpc:1.1

org.apache.maven.shared.dependency.tree.DependencyTreeBuilder
It seems like maven doesn't download the required dependency for some reason.
I have a local nexus configured that contains the jar, but i get the same result regardless if I have that profile active in my settings.xml or not.
How should I configure maven in order for it to try to download the dependency?
This was resolved by running:
mvn sonar:sonar -U
Apparently there was some corruption in the .m2 directory.
This is probably a newbie question, but I'm new to Maven.
I'm trying to build Gerrit's replication plugin, "since the master branch (and thus Gerrit 2.5) no longer supports replication out of the box."
So I did clone https://gerrit.googlesource.com/plugins/replication and executed mvn clean install inside the new directory. The error message is:

It looks like this URL isn't valid: https://gerrit-api.commondatastorage.googleapis.com/release/ -- but like I said, I'm new to Maven so I'm not sure how to proceed. I did some research, but I don't know what I'm looking for.
Any pointer would be highly appreciated. Thanks in advance.
A couple of things -
You are missing the gerrit-plugin-api.jar. This currently isn't provided upstream, so you must build it yourself. I believe running mvn install from a Gerrit repository will package and add this jar to your system.
You don't want to run install, you just want to run package on the plugin. mvn package will put the .jar in the target/ folder, which you then copy to your plugins folder inside your Gerrit installation.
Good luck!
Like Brad mentioned, I am missing the gerrit-plugin-api.jar. Unfortunately, I was not able to build it, since the Gerrit repos seem to be facing issues lately, as mentioned in other threads (this one, for instance - from two days ago).
Anyway, below are my additional steps based on Brad's answer (hopefully this may help others):
git clone https://gerrit.googlesource.com/gerrit
cd gerrit/gerrit-plugin-api/
mvn clean install

EDIT
These are the steps that worked for me, in case someone else faces the same issue.
git clone https://gerrit.googlesource.com/gerrit
Check available 'versions'
git branch -r
git checkout -b 2.5 origin/stable-2.5
The steps didn't work on the master branch in my environment, and I'm using 2.5...
So yeah, 2.5.
cd gerrit
mvn clean install
This will rebuild the entire universe, go grab a cup of coffee. :)
.. when done
cd gerrit-plugin-api/
mvn package
This also takes some time...
If everything goes fine, you can copy the jar at the target folder, like:
cp target/<large-name>.jar ~/replication.jar
Finally install it (from ~):
ssh -p 29418 localhost gerrit plugin install -n name \ - <replication.jar
Details on how to install Gerrit plugins are here.
The thing is, now I'm getting another error, something like:
"A binding to (something) was already configured at (something)."
But that's another story / thread / post...
Thanks and good luck!
Do a mvn -P all clean install on the toplevel, not inside gerrit-plugin-api.
The fastest way to fix is is to change the pom.xml and use a version that is not a snapshot. I was trying to build the delete-project for the stable-2.6 branch and was facing the same issue. All that needs to be done is to change the Gerrit-ApiVersion:
<Gerrit-ApiType>plugin</Gerrit-ApiType>
- <Gerrit-ApiVersion>2.6-SNAPSHOT</Gerrit-ApiVersion>
+ <Gerrit-ApiVersion>2.6-rc2</Gerrit-ApiVersion>
</properties>
<name>Delete Project Gerrit Plugin</name>
Building off of #Conaaando's answer, I performed these exact steps and successfully am using the plugin. Steps courtesy of http://asheepapart.blogspot.com/2013/12/how-to-build-gerrit-replication-plugin.html
git clone --recursive https://gerrit.googlesource.com/gerrit
You need the --recursive here because the plugins are actually git submodules and won't otherwise be cloned along with your repo.
If you've already cloned, you can run git submodule init; git submodule update
cd gerrit
git checkout -b stable-2.7 origin/stable-2.7
mvn install -DskipTests=true -Dmaven.javadoc.skip=true
It's not necessary to skip the tests or generating Java Doc, but it will greatly improve your compile time and decrease the amount of memory maven uses
cd gerrit-plugin-api
mvn package -Dmaven.javadoc.skip=true
This creates the jar that will be necessary for the replication plugin to get built
cd plugins/replication
mvn package -Dmaven.javadoc.skip=true
At this point, you have compiled and packaged the replication jar! All you need to do now is register it with your Gerrit server. For simplicity, I'll pretend your gerrit server is running at gerrit.example.com. These steps copy the replication jar to your review server and then instruct the review server to install the plugin from that copied location.
scp target/replication-2.7.jar gerrit.example.com:/tmp/
ssh -p 29418 gerrit.example.com gerrit plugin install -n replication /tmp/replication-2.7.jar
A team member has shared his project with me on bitbucket and he used maven to manage his dependencies. After cloning the repo (using mercurial) into my workspace (Eclipse) and downloading maven, m2e and all the other required set up files i was able to get all of the project libraries except for 4.
After downloading the project, i ran several mvn commands to clean, install and hopefully download these missing jars. When i ran mvn -e command i get this long error that does nothing to help. Do i have to find and download these 4 jars and put them in my maven repo?
Command output: mvn -e

EDIT:
I just need to share my local repository with all other team members that clone my project. External jars that dont use maven have to be manually installed into my local repo, this creates a problem because i cant share my local repo? Any ideas
You can either install these JARs in your local repository, or setup an own (possibly private) maven repository for you to share with your team. Sonatype provides with Nexus OSS an open-source based software to easily set up a repository (which also proxies remote ones if you like).
I try to develop one jenkins (a.k.a hudson) plugin, and follow the Tutorial, and generated source code tree after mvn -cpu hpi:create command.
While when I do "mvn package", it reports error like

from the specified remote repositories:
nexus (http://maven.nexus.local:8888/nexus/content/groups/public)
for project org.apache.maven.plugins:maven-enforcer-plugin
From my nexus server, it has maven-enforcer-plugin:1.0 version only, but this dependence is generated from jenkins by default, anyone can help me to solve it ?
(How) Can I change to plugin-1.0 version.
what can I add in nexus server
I just have basic knowledge of maven.
I fixed it by myself by doing two things.
1. Added Apache snapshot from here into my nexus repo group besides those setting in Tutorial
2. It seems my local maven repo is messed up as well, so I can clean it up and reload from nexus.
And it still use maven-enforcer-plugin:pom:1.1-SNAPSHOT plugins.
Hope it helps you as well.
