I am unable to build the project using Apache-maven 3.2.2 and As i am new to the maven i am not able to find the issue. Please provide some solutions to resolve it.
And the error as follows:
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR] Unresolveable build extension: Plugin
org.apache.maven.wagon:wagon-ftp:1.0-beta-2 or one of its dependencies could

(http://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host
repo.maven.apache.org -> [Help 2]
and my maven version as follows:
C:\Users\xyz>mvn -version

The problem is with your maven path , you have to give bin as your maven path
In your pom.xml, try to find this dependency.
<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ftp</artifactId>
<version>1.0-beta-2</version>
</dependency>
and you can change it with the following artifact;
<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ftp</artifactId>
<version>2.10</version>
</dependency>
if it does not work, the problem is with your internet settings, as Tunaki said.

I have a Nexus 3 which I deploy some artifacts from Jenkins with "mvn deploy". I have A LOT of modules 500+. The build looks kind of like this:
mvn clean package -DskipTests -DskipITs -T C1
mvn install -DskipTests -DskipITs -T C1
mvn deploy --quiet -DskipTests -DskipITs -Dmaven.validate.skip=true -Dmaven.compile.skip=true -Dmaven.test.skip=true -Dmaven.package.skip=true -Dmaven.integration-test.skip=true -Dmaven.verify.skip=true -T C1
The problem is that from time to time my artifacts have a timestamp while the metadata has a different timestamp. 1 second difference usually.
This is what I see in nexus at https://mynexus.com/repository/snapshots/com/company/my-artifact/1.0.0-SNAPSHOT/maven-metadata.xml
<?xml version="1.0" encoding="UTF-8"?>
<metadata modelVersion="1.1.0">

Judging the maven-metadata.xml, the artifact URL should be this:
https://mynexus.com/repository/snapshots/com/company/my-artifact/1.0.0-SNAPSHOT/my-artifact/1.0.0-20170613.140447-1.war
But it is not. Instead, the artifact is at this location:
https://mynexus.com/repository/snapshots/com/company/my-artifact/1.0.0-SNAPSHOT/my-artifact/1.0.0-20170613.140446-1.war

The version of maven-deploy-plugin is 2.8.2
What am I doing wrong? How can I fix this?
Thank you!
This is a bug in Maven 3.5.0 and and will be resolved whenever 3.5.1 is released.
The original bug-report targed the deploy-plugin (https://issues.apache.org/jira/browse/MDEPLOY-221) however it's an issue with maven core: https://issues.apache.org/jira/browse/MNG-6240.
We hit the same issue at my work and after some digging and searching on mavens issue tracker I found the above links. I would suggest downgrading while waiting for 3.5.1 to come out.
I tried to build LogicalDoc 6.7.1 with JDK 1.7, maven 3.0.3 and Ant 1.7

As the error message states, your maven build is failing because something in D:\maqtary\logicaldoc-6.7.1-src\build\poms\pom.xml is telling it to use the maven plugin org.apache.maven.wagon:wagon-ssh, which doesn't exist in maven central repository, or your local repository, and thus the build fails.
It looks like said plugin can be found here
I'm new to maven and i'm trying to use the following command :
mvn clean install -DskipTests=true
but i get the following error :

I have absolutly no idea of what i'm missing. Here is my pom.xml

I create a simple maven project in eclipse(indigo), it reports an error:
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.3 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.4.3
I found maven-resources-plugin:2.5 in local repo.
I don't understand why my project needs 2.4.3 but not 2.5?

I solved it,
just create src/main/java, src/main/resources, src/test/java, src/test/resources
The maven-resources-plugin will disappear.
I'm trying to build a java project using maven. In the pom.xml file at the root of the project I have the following lines:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<debug>true</debug>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
but when I try to build with mvn -DskipTests -U install, I get the following error: static import declarations are not supported in -source 1.3
maven is not using the source and target (1.6) that i've specified in the pom.
java -version

Is there anywhere else that maven might be getting its default source and target settings from? Why isnt it using the settings from the pom?
Here is a snippet of error message when maven is ran in debug mode:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project LeaderLines: Compilation failure

Try setting the source level and source encoding with the following properties:
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
Try to clear you local Maven repo and run your build again (maybe, try also to run it with '-o' option)
