How to make Nexus repository have multiple proxy repositories? - java

I set up nexus as local maven repository. I want two proxy repositories. One get dependencies from maven central another from reficio repository.
I created a new proxy repository maven-reficio and added it to the group repository,maven-public. Also I have edited my settings.xml as seen in the following post.
However, I still cannot get the dependencies from reficio repository and dependencies not cached. Please advise.

My settings.xml :
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

You should configurate the settings.xml like this:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://localhost:8081/nexus/content/groups/public</url>

</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
And then configuration other repository in your nexus...

Why maven create folders on my project root?

im facing this problem and I dont know what to do. We import a project from git to Intellij, and when we execute mvn clean install, maven start creating all dependencies folders on our project root. This only happpends on one of our PCs, and we have no idea why:

Thanks!

This sounds like maven is configured to use the project root/the current directory as the location for the local repository.
Check settings.xml in ~/.m2, possibly rename it and try again.

I tried to add proxy but no use. tried to add mirror as well but not working. Please let me know if you faced and fixed the same issue

Spring-boot-maven-plugin doesn´t deploy to one of two artifact repositories

I have two artifact repositories, one for snapshots and other for releases. The older project uses maven-release-plugin and successfuly deploys to both repositories depending on the parameters passed.
But I have a Spring Boot application which uses spring-boot-maven-plugin, and with the same configuration it only deploys to my snapshot repository, even though I pass release as parameter. I´d also like for it to remove -SNAPSHOT of the resulting artifact.
I´m using Jenkis for build and deployment.
Can anyone shed a light on this? I´ve researched but came out empty. Please ask me if you need any more information. Thanks in advance!
These are the parameters in my 'Goals and options' section on jenkins for both applications.
deploy -P release --batch-mode release:prepare release:perform -DscmCommentPrefix=RELEASE -DignoreSnapshots=true -D https.protocols=TLSv1.2

For your non-interactive release, it appears that you're missing a few properties to actually ensure that the version is incremented.
mvn --batch-mode -Dtag=my-proj-1.2 release:prepare \
-DreleaseVersion=1.2 \
-DdevelopmentVersion=2.0-SNAPSHOT
Those -D flags are important; they set the release version (thus removing the -SNAPSHOT from your version) and set the new release version.

Spring-boot-start jar load error in maven project on Netbeans

I donwloaded a new spring boot application (version 2.0.0) from https://start.spring.io/ and I tried to build it using netbeans IDE.
During the maven build I got the following error :
The build could not read 1 project -> [Help 1]
The project com.deepit.springboot.example:spring-boot-in-deep:0.0.1-SNAPSHOT (~=NetBeansProjects\spring-boot-in-deep\pom.xml) has 1 error
Non-resolvable parent POM: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.BUILD-SNAPSHOT from/to spring-snapshots (https://repo.spring.io/snapshot): repo.spring.io and 'parent.relativePath' points at no local POM # line 14, column 10: Unknown host repo.spring.io -> [Help 2]
To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.
Do you have an idea about the cause of this error ?

To resolve this I add a proxy in the settings.xml file in the config folder of maven.
To know the location of your settings file, start maven with -X option (debug) and examine the beginning of the output.

Can you post the contents of your POM?
Update: POM looks ok. I would guess a connection error (even though you said you tested it).
