As as follow-up to the Helios compatible release of Liferay IDE (v1.0.1), I wanted to let everyone know that there is another installation method now available through the Eclipse marketplace. The cool thing is that installing from the marketplace is simple by using the new marketplace client in the Eclipse Helios release. The best part of the process is that you don't need to know the update-site only the name of what you are trying to install. Below are a couple of screenshots of the process:
Note: The Eclipse marketplace is only available in Eclipse Helios release and previous versions like Galileo don't have that feature.
