Eclipse Oomph Windows 64位安装程序下载Linux工具

Question

I am installing eclipse using the Oomph installer tool.

I am seeing in the logs that linux tools are getting downloaded, which is taking time as well.

I would like to understand the reason. If we are installing Eclipse using Oomph we are not sure of what plugins and jars will be downloaded. How does this work?

Collecting 1 artifacts from http://download.eclipse.org/linuxtools/updates-docker-nightly/

Downloading org.bouncycastle.bcprov

Fetching org.bouncycastle.bcprov_1.52.0.v20160915-1535.jar from http://download.eclipse.org/linuxtools/updates-docker-nightly/plugins/

Answer 1

Java lives on dependencies. For instance, bouncycastle is a crypto library. It's used for many things, including securing connections. It's probably a dependency of at least 10 other tools in Eclipse.

Whenever a Java tool in Eclipse declares a dependency, the installer is going to go out to a public repository and fetch that dependency so your program will build properly. That's generally true of installers and build tools beyond Eclipse as well.

Answer 2

Any Eclipse installation based on Oomph uses a "Set Up Model" which is just a declarative description of which Eclipse plugins from which "p2 repositories" (= URLs of site that offer Eclipse plugins) are downloaded.

Are you by any chance seeing this problem when using (my...) https://github.com/vorburger/opendaylight-eclipse-setup ? ;-) I used to include " http://download.eclipse.org/linuxtools/updates-docker-nightly/ , but have long since removed it again .
