A warning message appears every time you install Maven:

Eclipse is running in a JRE, but a JDK was requiredsome Maven plugins may isn't work when importing projects or updating sour Ce folders.

Solve the problem in two steps:

1. Check the JRE that eclipse is using

' Java ', ' Preferences ', ' Window ', ' installed JREs ' determines that the JDK is being used rather than the JRE.

2. Configure Eclipse.ini

Review the Eclipse configuration file and Add/edit the following code:

-Vmc:\progra~2\JAVA\JDK1.6.0_16\JRE\BIN\JAVAW

Precautions:

1. First row parameter name, second behavior value, cannot be written to the same line

2. For the value of the second row, because no spaces are allowed, use progra~1 or 2 instead of program Files (x86).
If under Program files, use Progra~1, if under x86, use Progra~2

3. The position in the file can not be put to the last (after-vmargs), do not rest assured directly placed in the file, such as:

-Vmc:\progra~2\java\jdk1.6. 0_16\JRE\BIN\JAVAW-startup ... .. --launcher.defaultactionopenfile-vmargs-dosgi.requiredjavaversion=1.5-xms240m- xmx912m
