I'm trying to build Valkyrie RCP from the 1.2 release. According to their instructions, it should be easy: "Just clone the repository, and then use a mvn install command."
However, when I try the command, I get the following error:
[ERROR] Failed to execute goal on project valkyrie-rcp-core: Could not
resolve dependencies for project dk.navicon:valkyrie-rcp-core:jar:1.2:
Failure to find com.l2fprod:l2fprod-common-all:jar:7.3 in
http://repo.maven.apache.org/maven2 was cached in the local
repository, resolution will not be reattempted until the update
interval of central has elapsed or updates are forced -> [Help 1]
I can see that l2fprod-common-all-7.3.jar is included in the dependencies folder but Maven seems to be unaware of that. How should I resolve this problem?
Actually, it's now possible to build it using Gradle, which doesn't have the dependency issues . Also, there's a dependencies folder with batch scripts to install the missing dependencies if you still wish to use Maven.
As of 2.0 Valkyrie RCP will use Gradle.
The problem is that the given version of that dependency does not exist in Maven Central only older versions.
They would probably suggest you do a mvn install first on the file in the dependencies folder, then.
Try go down in deps and do a
mvn install -DgroupId=com.l2fprod -DartifactId=l2fprod-common-all -Dversion=7.3 -Dpackaging=jar -Dfile=l2fprod-common-all-7.3.jar
That would get you past that point locally.
After that re-execute your project build with a -Uoption.
Long term is to find the artifact and include it in a repository that is searchable from your maven settings or project profile.

CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Cannot access central (https://repo.maven.apache.org/maven2) in offline mode and the artifact org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 has not been downloaded from it before.
Any chance you're running maven in offline mode? Please check that you don't use -o option.
If you have to work in offline mode you should first download all the required dependency (one time):
mvn dependency:go-offline
I am using Maven for my project. I have a parent project myProjectA and when I do mvn clean install it builds successfully. myProjectA has multiple children, one of which is "childA1". This childA1 calls a plugin childB1 from myProjectB.
The problem is that when I try to do mvn clean install on childA1 then it fails with error:
Plugin my-maven-plugin:0.1-SNAPSHOT or one of its dependencies could not be resolved: Failed to read artifact descriptor for my-maven-plugin:jar:0.1-SNAPSHOT: Failure to find org.wildfly.core:wildfly-core-parent:pom:myVersion in http://repository.jboss.org/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of jboss-public-repository-group has elapsed or updates are forced
I understand from the error that the dependency org.wildfly.core in my-maven-plugin is not found. This dependency does not appear explicitly in the pom of childA1 or childB1. So to try to solve my problem I added the dependency to childB1 and did mvn clean install on childB1, the dependency was resolved and build was successful. While doing this I saw that the dependency was in fact downloaded from http://mynexus/nexus/content/groups/public and not the jboss repository that childA1 tries to get it from.
I looked at the "effective pom" tab (in Eclipse) of childA1 and childB1 and there I saw that the correct repository, mynexus, was listed and not the jboss repository.
Other things I tried is running with -U and I made sure to build myProjectA before building childA1. Unfortunately this did not solve my problem. Any suggestions how to fix it are welcome.
I am trying to build a maven project. My other team members are able to build it without issues. I get the following errors:
[WARNING] The POM for org.hectorclient:hector-core:jar:1.0-3 is missing, no dependency information
available
[WARNING] The POM for org.hectorclient:hector-test:jar:1.0-3 is missing, no dependency information
available
Then the build fails with the error: Could not resolve dependencies for the project XYZ. What could be possibly going wrong?
Surely the jar is missing from your .m2 local repository.
Assuming the dependency is written in the pom.
What I suggest:
Case: When you have internet
fire mvn install that will follow your POM.xml and it will download all the necessary jars.
then fire mvn compile to build.
Case: You are having restricted internet connection that is restricting / no Internet
Take the repository + POM from other machine that is compiling successfully
then fire mvn -o compile
I assume it will solve your case.
#Vaibs You are correct. Adding to your answer:
"Check the settings.xml of yours and the others. If you are not able to download the dependencies from internet like the one you mentioned due to some reason then you will need to set up maven somewhere else and and fire "mvn install" there to get the latest dependencies and put those .m2 into yours."
I have a problem with jenkins version 1.500. i am trying to build a project with a dependency to another project of mine.
The error is:
[ERROR] Failed to execute goal on project projectname: Could not resolve dependencies for project projectname:jar:1.0.0: Failure to find reference-project:jar:1.0.0 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
If I build this project via console and Maven, the whole projects build succeed.
I checked the dependency jar file in the repository, it is there at the right place.
Does Maven have a own repository or did I miss something?
But under the Jenkins system settings, I chose "Default(~/.m2/repository)" and I did not check the checkbox "use own repository" at the project settings. Any ideas?
UPDATE
I created a extra job for the dependency in jenkins and called the Maven goal install and then everything works fine. Before this step I installed the dependency via Console and mvn install.
Why is there a difference? (i tried the given solution with delete and reinstall, but this did not help)
Simple solution delete the folder from the ~/.m2/repository which represents the artifact you've written about. ~/.m2/repository/${groupId}/... and rebuild. That happens sometimes if you have some problems during download of the artifact etc.
I too have similar problem and tried deleting the folder in ~/.m2/repository/
still its now downloading dependencies from remote repository location to local
Having zero experience with Maven, I am running a mvn clean install on a project and this is the error I get:
[ERROR] Failed to execute goal on project dnasequencing.CompaNY.com: Could not resolve dependencies for project com.CompaNY.dnasequencing:dnasequencing.
CompaNY.com:war:1.0-SNAPSHOT: The following artifacts could not be resolved: dsr-kepler:dsr-kepler:jar:0.0.1-SNAPSHOT, dsr-parser:dsr-parser:jar:0.0.1-

will not be reattempted until the update interval of Maven_Central_Repo has elapsed or updates are forced -> [Help 1]
Based on these error messages, what is an startingpoint I should take a look for finding what is going wrong?
You can force Maven to update snapshots with the -U flag.
As far as what is going wrong, you can always check out the actual Maven website with your browser and see if the dependency actually exists.
http://search.maven.org/
If the dependency is not hosted in Maven central, then it seems it is a local dependency that you have to install in your local cache (run mvn clean install from that project).
