在eclipse中安装maven并创建maven项目

Question

I am new to using maven project and i am trying to create a maven project and i followed the instructions to create one in eclipse and i gave the groupId and artifact id to it and clicked Finish, for which it gave me an error stating

"No marketplace entries found to handle maven-compiler-plugin:3.1:compile in Eclipse. Please see Help for more information."

For this issue i tried googling and stack overflow and i saw people asking other people to change the installation directory of maven inside

Window-> Preferences -> Maven-> Installation

I tried that and tried to update the maven project but still i have some errors, i am not able to setup my project, Could someone please help? I am attaching the errors herewith.

Answer 1

If a Maven project is configured to use ecj compiler, the following errors appear when importing the project into eclipse:

• No marketplace entries found to handle maven-compiler-plugin:2.3.2:compile in Eclipse. Please see Help for more information.

• No marketplace entries found to handle maven-compiler-plugin:2.3.2:testCompile in Eclipse. Please see Help for more information.

A fix should be trivial.

http://git.eclipse.org/c/m2e/m2e-core.git/tree/org.eclipse.m2e.jdt/lifecycle-mapping-metadata.xml reads:

    <parameters>
      <compilerId>javac</compilerId>
    </parameters>

It should read:

    <parameters>
      <compilerId>javac</compilerId>
      <compilerId>eclipse</compilerId>
    </parameters>

Reproducible: Always

Steps to Reproduce: 1. Unpack example zip provided 2. Try to import it to Eclipse: File->Import->Maven->Existing Maven Projects

Answer 4

First install Java and then create the maven project.

Install the stable Java version in the system.

If Java is not installed then these types of errors will be displayed.

No marketplace entries found to handle maven-compiler-plugin:3.1:compile in Eclipse.
