Eclipse Platform SDK vs Eclipse SDK（附Eclipse-platform下载地址）

（选择版本后往下拉有platform版本下载地址）

Mikhail Kalkov:

"Eclipse Platform SDK" is a subset to "Eclipse SDK" and intersects with "Eclipse Project SDK".
However, if you installed both "Eclipse Platform SDK" and "Eclipse SDK", don't uninstall "Eclipse Platform SDK" -- it'll kill your Eclipse installation...
and I've been having a lot of fun because of this today.

Mikhail Kalkov:

In my case, the mapping between names and id is as follows:
* Eclipse SDK: "org.eclipse.sdk.ide"
* Eclipse Project SDK: "org.eclipse.sdk.feature.group"
* Eclipse Platform SDK: "org.eclipse.platform.sdk"
What I found out from reading the suggested file is summarized below.

* "org.eclipse.sdk.ide" (Eclipse SDK) requires
a.jre.javase
config.a.jre.javase
org.eclipse.sdk.feature.group (Eclipse Project SDK)
org.eclipse.equinox.p2.user.ui.feature.group
org.eclipse.rcp.configuration.feature.group
toolingorg.eclipse.configuration,
toolingorg.eclipse.sdk.ide.configuration
toolingorg.eclipse.configuration.macosx
toolingorg.eclipse.configuration.macosx.x86_64
tooling.org.eclipse.update.feature.default
tooling.source.default
tooling.osgi.bundle.default

* "org.eclipse.sdk.feature.group" (Eclipse Project SDK) requires
org.eclipse.platform.feature.group
org.eclipse.platform.source.feature.group
org.eclipse.cvs.feature.group
org.eclipse.cvs.source.feature.group
org.eclipse.jdt.feature.group
org.eclipse.jdt.source.feature.group
org.eclipse.pde.feature.group
org.eclipse.pde.source.feature.group
org.eclipse.help.feature.group
org.eclipse.help.source.feature.group
org.eclipse.sdk (some unimportant classes)
org.eclipse.sdk.feature.jar

"org.eclipse.platform.sdk" (Eclipse Platform SDK) requires
a.jre.javase
config.a.jre.javase
org.eclipse.platform.feature.group
org.eclipse.platform.source.feature.group
org.eclipse.equinox.p2.user.ui.feature.group
org.eclipse.rcp.configuration.feature.group
toolingorg.eclipse.configuration,
toolingorg.eclipse.platform.sdk.configuration
toolingorg.eclipse.configuration.macosx
tooling.org.eclipse.update.feature.default
tooling.source.default
tooling.osgi.bundle.default

As we can see Eclipse Project SDK is quite big, and it gets pulled in automatically by Eclipse SDK,
whereas Eclipse Platform SDK is a streamlined alternative to Eclipse SDK in case you don't need source code and binaries for help, pde, jdt, cvs.
