I have Eclipse Java EE IDE Version: Mars Release (4.5.0),Build id: 20150621-1200. I want to install latest Spring IDE. Tried to install it from the Eclipse Marketplace option. After clicking install it shows a very slow progress bar of calculating requirements and dependencies. After sometime it shows the error message below ("cannot perform operation. Computing alternate solutions."). But after completing that it does not install any of it.

enter image description here

I have also tried from Install new software option with this url: "http://dist.springsource.com/release/TOOLS/update/e4.5/" . But it results in same error.

Also tried downloading STS (Spring tool suit ) and copying the plugin and features folder in the root eclipse directory. Yet nothing seems to work. So I am kind of stuck here.

Can anyone guide me what am I missing here? Thanks in advance.

    Please show the details of the error; it will tell us exactly what is blocking the installation. – E-Riz Mar 31 '16 at 18:20
  • Why don't you simply download STS directly from [Spring's site](https://spring.io/tools/sts/all) and install it? The newest version is based on Eclipse Mars.2 (4.5.2). – António Ribeiro Mar 31 '16 at 21:47
  • FYI for 2018 installs or later - you need to install STS 3 to get the spring perspective and most of the Spring items installed in the new menu. In addition to ensuring everything installs properly. If you installed STS 4 first, you can just install STS 3 plug-in as well from the Marketplace. – LightCC Dec 23 '18 at 04:04

I too faced the same issue but resolved by following below steps: 1) Goto Eclipse -> help -> check for updates[wait until all update process is over] 2) then try installing spring IDE from eclipse market place

  • Also, you may need to go into the marketplace and find your already installed STS 3/4 plugins, and click on the "installed" button, which will bring up a dialog where you can check for or install pending upgrades... – LightCC Dec 23 '18 at 04:05
