Eclipse Maven：没有“从 SCM 签出 Maven 项目”选项

Question

I have to compile and run a Maven project that some colleagues of mine developed some years ago. I'm using Eclipse Helios on Microsoft Windows Server 2008.

In their documentation about how to compile it with Eclipse, I read that I have to install on my Eclipse:

• Maven plugin (from http://m2eclipse.sonatype.org/sites/m2e )
• Maven plugin extra (from http://m2eclipse.sonatype.org/sites/m2e-extras )
• Subclipse plugin ( http://subclipse.tigris.org )

After installed these plugins, their document says to select the option "Checkout Maven Project from SCM" and other operations.

I've tried to install these plugins, but, first, I realized that they are antiquated. I discovered that Maven Plugin changed name and address (now is Maven Integration for Eclipse 1.2), and that Maven Plugin Extra does not exist anymore. Subclipse, instead, is available.

So I installed these plugins, but, afterwords, no "Checkout Maven Project from SCM" functionality was present on my Eclipse. Then I searched online to solve this problem, and I found this thread on StackOverflow.com . It suggested to install the Maven SCM handler for Subclipse . I've searched it on the plugin repository of Elcipse but it does not exist anymore.

Which Eclipse plugin may I use to get the "Checkout Maven Project from SCM" functionality on my Eclipse IDE?

Thanks a lot

Answer 1

When you go to Window -> Preferences -> Maven -> Discovery, you have a button "Open Catalog", which opens a plugin marketplace specific to the m2e plugin. There you'll find a plugin called m2e-subclipse, which should give you the appropriate options:

Answer 2

Change the installed sub version to have m2 plugin. then check out as maven shows up.

Eclipse Marketplace -> Installed -> Subversive SVN -> Change -> Subversive SVN Integration for the M2E Project (Optional) and install it.

see images below.

Answer 3

I have recently run into same issue and found solution, as preferences trick mentioned in this post did not work for me. All you need to do is to go back to your SVN installation (tested for subversive, guess similar for subclipse) and check m2e integration plug-in.

In my case: Eclipse Marketplace -> Installed -> Subversive SVN -> Change -> Subversive SVN Integration for the M2E Project (Optional) and install it.

Answer 4

我有一个解决方法，因为我无法在 Window -> Preferences -> Maven -> Discovery 中找到 m2e-subclipse。您需要查看项目。完成后，右键单击 Project Explorer 并导入->Maven- >Existing Maven Project 并选择签出的项目并单击Finish。

Just a heads up for anybody seeing this again for future versions of Eclipse.

Sonatype is no longer maintaining this:

You can either use the fork currently being maintainted in github [ https://github.com/subclipse/m2e] : https://dl.bintray.com/subclipse/releases/m2e/1.0.x/

Or you can use the eclipse maintained link for the eclipse version: https://download.eclipse.org/technology/m2e/releases/1.9/1.9.1.20180912-1601/

Install either one by using the "install new software" link in Eclipse above "Eclipse Marketplace"
