Error creating MAVEN project,

1. Project name with Maven Webapp

Solution:

2. Missing jar Package

Could not resolve archetype

Cause: The Maven-archetype-quickstart plugin or plugin is missing from the local library

Solution:

1. Baidu Download: Maven-archetype-quickstart-1.1.jar, put in the Maven installation directory lib, for example: D:\apache-maven-3.3.9\lib

2.cmd window Execution command (go to the path where the jar package is located):

3. Not even in the Central library

Could not calculate build plan

Reason: Http://repo1.maven.org/maven2 This central warehouse address has been blocked, can not access, so maven used plug-in and jar download failed, and your computer on the local repository, do not download the MAVEN plug-ins and so on

Solution:

1. Copy the local repository. M2 directory to your computer and set <localRepository> as. M2 directory in Maven conf settings.xml.

2. If you have a settings.xml (such as a nexus), you can configure the Nexus address to download it from above.

4. New project, pom file on red x:

Failure to transfer org.apache.maven:maven-artifact:pom:2.0.6 from Http://repo.maven.apache.org/maven2 is cached in The local repository, resolution is not being reattempted until the update interval of the central have elapsed or updates are F orced. Original error:could not transfer artifact org.apache.maven:maven-artifact:pom:2.0.6 from/to Central (HTTP// REPO.MAVEN.APACHE.ORG/MAVEN2): No connector available to access repository Central (http://repo.maven.apache.org/ MAVEN2) of type default using the available factories Pom.xml/hello Line 1 Maven Configuration problem

1.

Open window-->preferences-->myeclipse-->maven4myeclipse--->user settings copy the address inside the local repository.

1. If you don't have a myeclipse, you'll find:

   c:\users\{your computer account}\.m2\repository (usually in this folder).

   Like mine: C:\users\long\.m2\repository.

2. Find the repository file and search for maven*.lastupdated. Delete all the documents that have been searched out.

3. Restart MyEclipse, right-click Project--->maven4myeclipse--->update project ...

4. Tick force Update of snapshots/releases, then OK exit, if still wrong, do not worry, wait for a while.

2. Error deploying MAVEN Project

1.JDK compilation Error

Unsupported Major.minor version 51.0

Cause: Compiled source JDK and Tomcat use a different version of JDK

FIX: Project------> Right------>properties------>java Compiler------>compiler Compliance level------> Select the JDK version you are using
