Maven Common Error Resolution method

1. The most important point, the use of domestic mirrors, such as oschina.net mirror;

2. Error:Could not resolve artifact Org.apache.maven.archetypes:maven-archetype-quickstart:pom:release

Eclipse builds the Maven-archetype-quickstart type of MAVEN project with the error above because there is no jar package for that type and cannot be downloaded.

Workaround:

1> from http://maven.oschina.net/content/groups/public/org/apache/maven/archetypes/maven-archetype-quickstart/

Download the latest version of Maven-archetype-quickstart-1.1.jar

2> to the download directory to perform the installation:

MVN install:install-file-dgroupid=org.apache.maven.archetypes-dartifactid=maven-archetype-quickstart-dversion= 1.1-dpackaging=jar-dfile=maven-archetype-quickstart-1.1.jar

3. Error: a jar package always fails to download successfully

such as the Netty-all package, there is only one in the Reposity directory D:\java_libs\repository\io\netty\netty-all\4.0.33.Final . lastupdated suffix file .

This is because MAVEN will generate a. lastupdated suffix file when it cannot find a resource in the download repository. If this file exists, MAVEN will not download the new resource even if it is replaced by a resource repository.

We can delete it and then save the Pom.xml file and let him download it again. If not, you can manually download the Netty-all-4.0.33.final.jar package and put it in:

D:\java_libs\repository\io\netty\netty-all\4.0.33.Final\

When you save the Pom.xml file, you can:
