STS 4.1.2 breaks Eclipse 4.10 Mylyn

STS 4.1.2 breaks Eclipse 4.10 Mylyn local task creation!

Either

1. install full STS 4.1.2 and then add Mylyn via Eclipse Marketplace or the p2, or
2. install Eclipse 4.10 JEE (Mylyn included) and add STS 4.1.2 via Eclipse Marketplace

Observe:

1. New Local Mylyn Task doesn’t save any info, e.g. a new task name, etc.

Workaround (also problematic):

1. Install Eclipse 4.10 JEE (Mylyn included) and add STS 4.1.2 via
   https://download.springsource.com/release/TOOLS/sts4/update/e4.10/

Observe:

1. Mylyn Local Task creation is ok
2. Eclipse Check for Updates gives the following error:

Unable to read repository at https://download.springsource.com/release/TOOLS/sts4/update/e4.10/compositeContent.xml.

This is a huge blocker! Please fix! Thank you!

Ok, you are completely right, I can reproduce that behavior. My bad, tested not enough and not looked at the right things before. The easiest and fastest way to fix this right within your environment is to install a fixed version of the LSP4E component (the one that got the fix). You can do that via Install New Software and use this p2 repo URL:

https://download.eclipse.org/lsp4e/snapshots/

Then select the component Language Server Protocol client for Eclipse IDE (Incubation) (it should show up as version 0.9.0.something). Select that component and press install. The dialog will tell you that instead of an install it will perform an update since you have that component already installed - which is absolutely correct. Continue, install, and restart. After that, the Mylyn integration should work again just fine.

Hope this helps!

My pleasure! And thank you for your hard work!

I think for those who want to stay with the release version, the initially provided workaround should be fine, given the STS url is disabled till the next STS release.
