I am trying to compile the project https://github.com/spring-cloud/spring-cloud-aws but the parent project has references to flatten-maven-plugin thus i am getting the error.
If this plugin is public i am not sure why i am getting the error as below. I am not able to get rid of this plugin. I opened a ticket on the git project but as it may not gather any answer.
Error resolving version for plugin 'org.codehaus.mojo:flatten-maven-plugin' from the repositories [local (C:\Users\ranajit.jana\.m2\repository), central (https://repo.maven.apache.org/maven2)]: Plugin not found in any plugin repository pom.xml /spring-cloud-aws-**** line 1 Maven pom Loading Problem
I am compiling this code as i want to make some changes.
Anyone has idea what can be done ?
=============================
This is resolved now.
This is was repo issue the plugin repo was pointing to repo1.maven.apache.org/maven2 which could not resolve this plugin.
I had to add the following to resolve this issue..
This is added as one additional plugin repo
<pluginRepository>
<id>maven-plugin-repo-mvn</id>
<name>Maven plugin repo maven</name>
<url>https://repo.maven.apache.org/maven2</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
Open the .m2/repository and proceed to the path org/codehaus/mojo/flatten-maven-plugin/. There delete the subdirectory version number. and all contained files. Maven will automatically download them the next time they are required.

am getting this error in my pom.xml file
Missing artifact org.springframework:spring-core:jar:5.0.0.M5
How do I solve this can anyone help me.
Thanks in advance.
The first answer is the correct one. you have to add the following repository to ur pom file.
<repositories>
<repository>
<id>spring-milestone</id>
<name>Spring Milestone Repository</name>
<url>https://repo.spring.io/milestone</url>
</repository>
</repositories>
To resolve this probleme you need to add the right repository to your pom.xml
<repositories><repository><id>spring-milestone</id><name>Spring Milestone Repository</name><url>https://repo.spring.io/milestone</url></repository></repositories>
The issue here is maven was not able to download the jar. TO resolve this first locate your .m2 directory and traverse to org -springframework and delete the folder spring-core and then from your eclipse right click on the pom.xml and click on update project. It will again download the required dependency.
This is not a question but a simple maven dependency solution of oltu openid connect that I like to share. I found it might be helpful to other as there's not too many resource about it on the web.
I was having a problem with oltu openid connect dependency in maven (pom). Somehow I found its groupid, artifact, and its version. But whenever I insert the dependency in pom, eclipse notifies me with missing artifact. The problem seemed like this:
The problem was as above mentioned that the dependency was not available in maven central repository. As I searched through web, I found those dependencies are hosted in other repository which is http://repository.idega.com/maven2/. After that, the solution was just to include this repository in your pom like shown below:
Try using the Apache Snapshot Repository:
<repositories>
<repository>
<id>apache.snapshots</id>
<name>Apache Snapshot Repository</name>
<url>https://repository.apache.org/snapshots</url>
<releases>
<enabled>false</enabled>
</releases>
</repository>
</repositories>
I am using Eclipse with Maven (using m2eclipse) and attempting to add the EclipseLink repository.
Within my pom.xml I have set the following:
<repositories>
<repository>
<id>eclipselink</id>
<url>http://www.eclipse.org/downloads/download.phpr=1&nf=1&file=/rt/eclipselink/maven.repo</url>
</repository>
</repositories>
I then navigate to the Maven Repository Window and right click the repository and select Full Index Enabled.
This results in the following message being displayed:
4/23/11 1:45:53 PM BST: Updating index eclipselink|http://www.eclipse.org/downloads/download.php?r=1&nf=1&file=/rt/eclipselink/maven.repo
4/23/11 1:45:54 PM BST: Unable to update index for eclipselink|http://www.eclipse.org/downloads/download.php?r=1&nf=1&file=/rt/eclipselink/maven.repo
Any help in solving this problem would be appreciated.
If you call that page you will get an 404 page not found...so the url must be wrong.
There may not be anything to worry. It is possible that Eclipselink repository is not having a repository index file which is requested by m2eclipse.
What is important is to check if dependencies specified in your pom, present in Eclipselink repository are getting downloaded correctly.
You have a typo in URL:
It should be:
http://www.eclipse.org/downloads/download.php?r=1&nf=1&file=/rt/eclipselink/maven.repo
You missed question mark.

Can't find the "org.eclipse.persistence" Maven dependency
I am trying to build the sample application for spring batch 2.1.6. (ie. spring-batch-2.1.6.RELEASE/samples/spring-batch-samples) using maven but am getting this error for a missing plugin:
[ERROR] Plugin
com.springsource.bundlor:com.springsource.bundlor.maven:1.0.0.RELEASE
or one of its dependencies could not be resolved: Failure to find
com.springsource.bundlor:com.springsource.bundlor.maven:jar:1.0.0.RELEASE
in http://repo1.maven.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 ->
Is there another repository I can set up to get this plugin? I am a bit suprised to be getting this errror as this is the latest realease version of spring batch.
Here is the repository section from the pom as it came in the download:
<repositories>
<repository>
<id>com.springsource.repository.bundles.external</id>
<name>SpringSource Enterprise Bundle Repository - SpringSource Bundle External</name>
<url>http://repository.springsource.com/maven/bundles/external</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
The project's parent pom has a bootstrap profile which contains the necessary repository definitions. Build the project with the command mvn test -P bootstrap and it will download the dependencies.
P.S. This is explained in the readme's instructions that how to build Spring Batch. It would be good if they would also tell how to do it in the instructions for using the samples - maybe you could file a bug report?
i am using maven3 and was able to solve this problem by adding this to my pom:
<pluginRepositories>
<pluginRepository>
<id>plugin.repo.maven.central2</id>
<url>http://objectstyle.org/maven2/</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
The Spring batch Admin sample build is broken for sure. At least as of today.
The -Pbootstrap doesn't help and adding the repos in that profile in my local settings doens't help either.
When I attempted to build spring-batch-admin-sample, I found that I was missing dependencies of spring batch!
So I went to build that. There I found that I was missing org.neo4j:neo4j-cypher-dsl-1.9.M04 and also gemfire.7.0.1.jar. Adding repos doesn't help because of the maven2/3 incompatibility issues.
So a sure way to fix this is to go to each repo, download the missing dep and mvn install-file them.
So get the neo4j one here:
http://m2.neo4j.org/content/repositories/releases/org/neo4j/neo4j-cypher-dsl/1.9.M04/
Get the gemfire one from here:
https://repo.springsource.org/gemstone-release-cache/com/gemstone/gemfire/gemfire/7.0.1/
And then I ran into a foundrylogic.vpp dependency that I found here:
http://objectstyle.org/maven2/foundrylogic/vpp/vpp/2.2.1/
Don't forget to get the corresponding poms also to keep it clean and get all the transitives, if any.
Use the mvn install-file plugin described here to get all three deps to your local repo.
http://maven.apache.org/plugins/maven-install-plugin/usage.html
Now spring-batch should build clean.
Now if you go to build spring-batch-admin it will still fail because it depends on spring-batch-core-2.2.3.BUILD-SNAPSHOT whereas what we just built was version 3.0.0.BUILD-SNAPSHOT.
So go to spring-batch-admin-parent's pom and modify the pom like so:
<!-- <spring.batch.version>2.2.3.BUILD-SNAPSHOT</spring.batch.version> -->
<spring.batch.version>3.0.0.BUILD-SNAPSHOT</spring.batch.version>
And then step back to spring-batch-admin and mvn clean install should build the sample.
Hope this helps someone!
I installed maven 3.2.1 and it works.
I've tried to build Tycho now for a couple of hours and just can't get it to work. I've followed these instructions:
https://docs.sonatype.org/display/TYCHO/BuildingTycho
So, I've downloaded Eclipse 3.6RC2 and Delta-packs linked from this instruction (is it for 3.5 only?):
http:// (remove space) aniefer.blogspot.com/2009/06/using-deltapack-in-eclipse-35.html
I've added the DeltaPack to the TargetPlatform inside of the Eclipse-installation.
I've installed Maven: Apache Maven 3.0-beta-1 (r935667; 2010-04-19 19:00:39+0200)
I can run the first bootstrap of the build, but the second fails:
mvn clean install -e -V -Pbootstrap-2 -Dtycho.targetPlatform=$TYCHO_TARGET_PLATFORM
ERROR] Internal error: java.lang.RuntimeException:
Could not resolve plugin org.eclipse.core.net.linux.x86_null -> [Help 1]
I've tried different stuff, I built an older revision against 3.5 as in this blogpost:
http:// (remove space) divby0.blogspot.com/2010/03/im-in-love-with-tycho-08-and-maven-3.html
and that actually built a running maven, but that version then can't find the tycho plugin:
org.apache.maven.plugin.version.PluginVersionResolutionException: Error resolving version for plugin 'org.codehaus.tycho:maven-tycho-plugin' from the repositories [local (/Users/viktor/.m2/repository), central (http://repo1.maven.org/maven2)]: Plugin not found in any plugin repository
I thought that the point was that the plugin was going to build in when I had built a Tycho-dist…?
Sorry about the links, stackoverflows spam-protection doesn't let me post more than one url yet
The Tycho documentation is pretty bad, to set the record straight, Tycho is included in the Maven repositories by default now; declaring it in your POM will automatically download it and allow you to use it.
To cut to the chase, this is all you have to put in your Maven POM to use Tycho, and then next time Maven uses this POM for a project, it will get Tycho if you don't already have it and use it for the build. At the time of this writing, 0.12.0 is the latest stable release.
<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-maven-plugin</artifactId>
<version>0.12.0</version>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
Now, say, you would like to use an "unstable" Tycho, like <version>0.13.0</version>. Then you would want to change the version number in the plugin to the appropriate value, and then add this (The latest Tycho repository) to your POM:
<pluginRepositories>
<pluginRepository>
<id>sonatype-release</id>
<url>http://repository.sonatype.org/content/groups/sonatype-public-grid
</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
That simple.
With the move to eclipse.org, we also invested in better documentation for contributors:
