I use the following Eclipse Neon.2

  • Eclipse Java EE IDE for Web Developers
  • Version: Neon.2 Release (4.6.2)
  • Build id: 20161208-0600
  • Eclipse path: C:\eclipse-jee-neon

and I tried to install the following Eclipse Plugin (via Marketplace or with drag and install directly from the website)

  • Spring Tool Suite (STS) for Eclipse 3.8.3.RELEASE and I receive the following error:

enter image description here

As an alternative I tried the Spring IDE 3.8.3.RELEASE plugin and got exactly the same error.

Any ideas? Thank you in advance.

The problem was that the following two .jar archives were corrupted:

  • com.fasterxml.jackson.core.jackson-annotations_2.5.0.v201504151636.jar
  • com.fasterxml.jackson.core.jackson-core_2.5.0.v201504151636.jar

The solution (which worked in my case) was:

  1. Download the two artifacts manually for example from University of Kent UKMirror Service
  2. Replace the two corrupted artifacts in C:\Users\smo.p2\pool\plugins\ with the manually downloaded ones
  3. Reinstall the plugin over the Eclipse Marketplace
