Cannot assign requested address: connect - java

I'm getting this error when I call any Maven command:
[ERROR] Plugin org.apache.maven.plugins:maven-enforcer-plugin:3.1.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-enforcer-plugin:jar:3.1.0: Could not transfer artifact org.apache.maven.plugins:maven-enforcer-plugin:pom:3.1.0 from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-enforcer-plugin/3.1.0/maven-enforcer-plugin-3.1.0.pom: Cannot assign requested address: connect -> [Help 1]
Things that I've already checked:
1. Windows Firewall is not blocking outbound/inbound requests
2. Not behind any proxy
3. Connected to the internet
4. Settings file credentials and repo url OK <settings>

5. Can access repo using browser
6. Cleaned caches
This was also happening with Gradle - this: Cannot assign requested address: connect - , before I switch the project to be under Maven control, so I'm guessing, some configuration in the machine (Machine is new).
Java version: 11.0.16
Apache Maven 3.8.7

Can anyone give me some hints ?
Thank You for your time.

Maven: Failed to read artifact descriptor error

I cloned a JAVA repo and when I tried to build it with "mvn install", I got the following error
Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.3.2.RELEASE from/to central (https://repo.maven.apache.org/maven2): Transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.3.2.RELEASE/spring-boot-starter-parent-2.3.2.RELEASE.pom and 'parent.relativePath' points at no local POM # line 6, column 13: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 2]
the repo "https://repo.maven.apache.org/maven2" is accessible in my browser when I open it in Chrome.
After some googling, I put a settings.xml file in the .m2 folder looks like this
<?xml version="1.0" encoding="UTF-8"?>
<settings>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>securecentral</activeProfile>
</activeProfiles>
<profiles>

Now when I run "mvn install", the error for spring-boot goes away. But I am facing this error now:
Failed to read artifact descriptor for org.apache.camel.springboot:camel-salesforce-starter:jar:3.4.2: Could not transfer artifact io.dropwizard.metrics:metrics-bom:pom:4.1.9 from/to central (https://repo.maven.apache.org/maven2): Transfer failed for https://repo.maven.apache.org/maven2/io/dropwizard/metrics/metrics-bom/4.1.9/metrics-bom-4.1.9.pom: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 1]
My question is, why do I need to manually add and in settings.xml and why I am still getting the error for camel? Thanks
You can try to run mvn -U clean install
-U according to Maven CLI options is for
Forces a check for missing releases and updated snapshots on remote
repositories
or try to delete the local repository folder. Sometimes it gets messed up when having network problems...
You can find your local repo folder in your .m2 folder (on windows: C:\Users<your_username>.m2)
You can delete the whole repository folder or just some part of it. After that just run the mvn clean install
PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target
Almost certain that root CA certificates on your system are outdated.
Try to update your JDK installation. Note that CA certificate used by your browser might not be same as JRE/JDK is using.
Without knowing more details about your system, it's hard to provide more accurate answer.
This answer provides possible workaround.
OK...got it working.
#rkosegi's answer put me on the right path. The root CA cert used by my browser is different than the one jdk uses. That's why I can view the repo in browser with no error but maven cannot access the repo.
Somehow my company (a financial institution) has a root CA cert overriding all the other root CA cert, that means, when I open any website (for example stackoverflow), the cert path always shows like this:
I am not a system admin and not sure how this is done, but anyhow, all I need to do is save the Root CA cert as a *.CER file and add it to the jdk's cacert folder.
After that, the command "mvn clean install" runs to complete with no error

How to use Jenkins credentials when running `mvn deploy`?

I have a Maven project and want to build it using mvn clean deploy so that the built artifact is deployed into a Nexus repository.
The access data (username and password) for that repository are stored in Jenkins credentials.
I want to call mvn deploy in Jenkins so that the credentials for that Nexus repository are read from Jenkins (not hardcoded in settings.xml).
How can I do it, if I cannot access settings.xml on the Jenkins server?
Update 1:
I created an entry in "Config File Management" (JENKINS_URL/configfiles/index) with following data:
Type: Maven settings.xml
Replace All: Yes
Server ID: myServer
Credentials: Credentials for the Nexus repository
Content:
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<servers>
<server>
<id>myServer</id>
<username>foo</username>
<password>bar</password>
</server>
</servers>
</settings>
myServer is also used in the pom.xml of the artifact I want to build:
<distributionManagement>
<repository>
<id>myServer</id>
<url>http://nexus.mycompany.com</url>
</repository>
</distributionManagement>
In the configuration of the job, I include those settings as shown below. Nexus settings.xml is the configuration from "Config File Management".
But it does not work -- I get "Forbidden" error when the build attempts to deploy artifacts to Nexus.
Update 2: When I run mvn -X deploy locally with the same credentials as in Jenkins (stored in my local settings.xml), I see following output:
[DEBUG] Failed to decrypt password for server XXX release repository: org.sonatype.plexus.components.sec.dispatcher.SecDispatcherException: java.io.FileNotFoundException: /XXXXXXXXXXXXXXX/.m2/settings-security.xml (No such file or directory)

However, the password in settings.xml is not encrypted at all:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

I found a report about similar error here.
You can use the Jenkins config-file-provider plugin ( link: https://plugins.jenkins.io/config-file-provider/ ) to create one or several Maven settings.xml files.
NOTE: Really this helps also if you need differents settings.xml for
different projects.
Then on the maven deploy step of your Jenkins project you can select to point to one of the settings.xml files defined ( instead of pointing to the general Jenkins server /.m2/settings.xml )

Maven not adding "Authorization" header

I'm trying to deploy artifacts to a protected by Basic Auth repository.
I specify
<distributionManagement>
<repository>
<id>some.repo</id>
<name>Some Repository</name>
<url>https://foo.bar</url>
</repository>
</distributionManagement>
in pom.xml
And
<servers>
<server>
<id>some.repo</id>
<username>user</username>
<password>{encoded password}</password>
</server>
</servers>
in settings.xml
But when I run mvn deploy it fails with the error: Not authorized , ReasonPhrase:. -> [Help 1]
If I use
<server>
<id>some.repo</id>
<configuration>
<httpHeaders>
<property>
<name>Authorization</name>
<value>Basic (hash)</value>
</property>
</httpHeaders>
</configuration>
</server>
instead - it works.
After inspection with Wireshark I discovered that in the first scenario (with login/password) Maven doesn't add Authorization header to the HTTP request.
Is it correct behavior? Am I missing something in the configuration?
Well, in this case, it was not Maven, but the server-side problem: server was not sending Connection: keep-alive header. With this header, the authorization flow works.
maven will only send username/password on requests where server responds with a
status code:401
header: WWW-Authenticate: Basic.

maven settings.xml properties are not seen in pom

i have in settings.xml following config
<profile>
<properties>
<nexus.host>http://localhost:8081/nexus/content/repositories</nexus.host>
</properties>
</profile>
this profile is set as active.
its used in distribution management section of pom
<distributionManagement>
<snapshotRepository>
<id>my-snapshots</id>
<name>my snapshots</name>
<url>${nexus.path}/snapshots</url>
</snapshotRepository>
<repository>
<id>my-releases</id>
<name>my releases</name>
<url>${nexus.path}/releases</url>
</repository>
</distributionManagement>
this works when i run it on local machine, but when the job is executed on jenkins it fails with
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM: Failure to transfer
com.myapp:sample:pom:1.1.0 from ${nexus.path}/releases was cached in

from/to my-releases (${nexus.path}/releases): Cannot access
${nexus.path}/releases with type default using the available connector
factories: WagonRepositoryConnectorFactory and 'parent.relativePath'
points at wrong local POM # line 3, column 13
unable to identify the cause of the error
I had the same issue in the past. To resolve this in Jenkins you will need to set the Maven argument so it can find the location of your settings.xml.
You will need to have the settings.xml in the application resources so Jenkins can find it.
To set the argument(In Jenkins, it should be under Goals and options):
-s src/main/resources/settings.xml
However in my instance the Jenkins administrators provided a separate version of maven so the application will have the needed settings.xml and there was no need to provide our own custom settings.xml.
On a side note, you might want to contact the Jenkins Administrators to ensure that they have implemented the proper configurations so Jenkins will be able to deploy the produced artifacts to the repository under the id you have specified.

Accessing maven repo requiring windows creds with a mac

I'm trying to accessing a server with a maven repo. From my windows machine at work I can access it with my company login. With my mac I can access the server if I connect to it and enter in my windows credentials.
Here is the part of my pom with the rep:
<repositories>
<repository>
<id>repo.id</id>
<url>file:////servername/MavenRepo</url>
<!-- use snapshot version -->
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
</repositories>
here is the part of the settings.xml that I'm using to try to set credentials to access that maven repo. What am I doing wrong?
<server>
<id>repo.id</id>
<username>domain\username</username>
<password>password</password>
</server>
The error is:
[ERROR] Failed to execute goal on project Company-Project: Could not resolve dependencies for project Company-Project:Company-Project:jar:DEVELOP-1.0-SNAPSHOT: Failed to collect dependencies at Company-ProjectName:Company-ProjectName:jar:1.0-SNAPSHOT: Failed to read artifact descriptor for Company-ProjectName:Company-ProjectName:jar:1.0-SNAPSHOT: Could not transfer artifact Company-ProjectName:Company-ProjectName:pom:1.0-SNAPSHOT from/to com.Company.maven (file:////Server.Company.corpnet.local/JenkinsMavenRepo): Repository path /Server.Company.corpnet.local/JenkinsMavenRepo does not exist, and cannot be created. -> [Help 1]
It seems that maven could not find the repository on the file system.
file:////Server.Company.corpnet.local/JenkinsMavenRepo): Repository path /Server.Company.corpnet.local/JenkinsMavenRepo does not exist
Have you mounted the repository file system correctly?
Check if you can access the directory /Server.Company.corpnet.local/JenkinsMavenRepo in the Terminal.
PS
I always would prefer a repository server such as nexus. Is that an option?
Turns out using windows as a filestore for a maven repo is proprietary. I setup a IIS server (http) pointing to that directory which resolves the issue.
