Eclipse+Maven src/main/java not visible in src folder in Package Explorer

I have solved this issue by below steps:

1. Right click the Maven Project -> Build Path -> Configure Build Path
2. In Order and Export tab, you can see the message like ‘2 build path entries are missing’
3. Now select ‘JRE System Library’ and ‘Maven Dependencies’ checkbox
4. Click OK

Now you can see below in all type of Explorers (Package or Project or Navigator)

src/main/java

src/main/resources

src/test/java
