2. Extra and open eclipse IDE

3. Click menu Help-> Eclipse Marketplace -> search 'Spring' -> click 'Spring Tool Suite (STS) for Eclipse 3.7.7RELEASE'-> click 'Install'

4. After the Spring installation finished restart eclipse IDE

5. The git and maven are broken.

Answer 1

I observed same type of issue with Maven plugin in eclipse when I copied my eclipse binary from one machine to another machine.

org.osgi.framework.BundleException: Could not resolve module: org.eclipse.m2e.core [479] Unresolved requirement: Require-Bundle: org.eclipse.m2e.maven.runtime; bundle-version="[1.7.0,1.8.0)" -> Bundle-SymbolicName: org.eclipse.m2e.maven.runtime; bundle-version="1.7.0.20160202-2118"; singleton:="false" org.eclipse.m2e.maven.runtime [491] Unresolved requirement: Require-Bundle: org.eclipse.m2e.maven.runtime.slf4j.simple; bundle-version="[1.7.0,1.8.0)" -> Bundle-SymbolicName: org.eclipse.m2e.maven.runtime.slf4j.simple; bundle-version="1.7.0.20160202-2118"; singleton:="false" org.eclipse.m2e.maven.runtime.slf4j.simple [492] Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=1.8))"

And the reason was the JDK7 on the new machine. When I pointed JDK8 in eclipse.ini, this issue get resolved.
