I'm trying to install maven on four projects. Let me explain the context :
I have a project (not mine), and I'm trying to run it but I have errors in the code and it's obviously maven errors. I have configured the Maven Environnement with this tuto : http://www.tutorialspoint.com/maven/maven_environment_setup.htm and it seems to work.
About the project, the entire project is dividing in four projects. I own only this four project, maybe they don't give me all the sources of the project (stupid) but why not.
So I'm trying to install maven in each projects and I have some errors, could you tell me what it means please ? And what should I do to resolve it ?

Project 3

Project 4

It is showing
Non-resolvable parent POM for fr.inra.grignon:persyst:1.0-snapshot
it means this indicates that maven did search locally for the parent pom, but found that it was not the correct pom or missing. if the project is multimodule it should have parent project.

I'm running this in the command line. Is it possible that I don't have maven configured correctly? Failing that, how do I get the full path to the problem dependency? I'd like to check if I can reach it through the browser.
I had an incorrect password to the artifact in my settings.xml
After JFrog released the source code for Artifactory 7.10.2, I tried to build it, without success.
The project seems to be a maven one (there is a pom.xml in the root project, so I guess so).
From the root of the project I gave the usual mvn package, but this resulted in an error:
$ mvn package

It seems that the project itself requires a local dependency, that it is not available to the tar.gz released though.
Looking at the 6.23.x source code there is a reference to artifactory-parent that is missing here, but I don't think it will compile using the old dependency.
Finally, I checked the build/ci folder, where there is a pipelines_build.sh script, but when launching it I have another error:
./pipelines_build.sh
./pipelines_build.sh: line 6: /tmp/build/ci/scripts/lib/buildInfoUtils.sh: No such file or directory
It seems that also here the tarball doesn't contain all the information in order to build the product.
For what it matters, I found the source code from this answer: Where is the Artifactory OSS source code located?
I'm doing something wrong? Can anyone help me building Artifactory?
You need to use JCenter not Maven central. Goto jcenter and download the settings.xml and then try again.
I started a new Maven project and try to get lagom to work on my Maven project. On my Run Configurations I have inputted lagom:runAll under Command Line. However, when I run my project I get the following error:

Does anyone understand why I am unable to spot lagom library? Thanks in advance for the help, cheers!
Problem is that Maven does not know anything about external plugins by default, and this extends to modules. Unless told so in the pom.xml (which implicitly implies any parent poms) a module has no knowledge of what happens in other modules.
Either you need to invoke lagom with the full artifact name or you need to configure lagom in your pom.xml (preferably using dependency management in the parent pom)
I have an open source project (https://github.com/mikera/vectorz) that uses a parent pom that is deployed on Maven Central (http://search.maven.org/#artifactdetails%7Cnet.mikera%7Cmikera-pom%7C0.2.0%7Cpom)
However I have started to get a strange error:

What could be causing this? Note that:
I'm 99% certain the parent pom has been successfully released on Central
clojars repo shouldn't even be required for the build
I'm running on Windows (though the issue seems to be affecting others on Linux too)
I have had projects like this working previously, however I recently upgraded to Maven 3.2.2 - could that be causing this error?
P.S. I tried checking my local .m2 repository and all it contains is a .lastUpdated file with the folloing content:
#NOTE: This is an Aether internal implementation file, its format can be changed without prior notice.

Any ideas how to resolve this?

Please let me how I can fix this.
Proxy usage is a factor, hope this will help: Maven Guide to Using Proxies
If your proxy requires NTLM authentication, you'll also probably need cntlm
The http://repo1.maven.org/maven2/ repository is down quite often, so maybe you were just out of luck that time.
