Using maven in myeclipse2014

Since the maven4myeclipse of myeclipse2014 is not very easy to use, it is not avoided that the two different versions of maven have different project rules, so the maven in myeclipse2014 is also changed to maven3.3.9 that we installed above

1. Configure maven 
   to open window–>preferences–>MyEclipse–>Maven4MyEclipse as shown below: 
   
   Click the Add button in the upper right corner and select the root directory of maven installed above (my directory is F:\maven\apache-maven-3.3.9)

2. Set up maven's central repository

   maven4myeclipse has the default warehouse address, in the user file .m2 directory, here we define the directory ourselves.

   First, create a new central warehouse (store the jar package to be loaded by the project), my directory is F:\maven\m2\repository, and then configure settings.xml from F:\maven\apache-maven-3.3.9\conf Copy the file to F:\maven, then open the copied settings.xml file, change the value in the localRepository tag to F:\maven\m2\repository, if the localRepository tag is commented out, open the comment, this The first step is to designate the central warehouse. 
   Then, enter the following interface 
   

Reconfigure settings.xml as shown.

In the last step, enter the following figure 

to replace the default jdk with the jdk configured in the environment variable, and set the Default vm arguments as shown in the figure below. 
 
At this point, the maven configuration in myeclipse2014 has been completed.
