Question

As I need to develop java, php, c++, I use several eclipse packages.

so I try to simple to copy several packages into one, and then I use these option to start the eclipse:
1. -clean
2. osgi.checkConfiguration=true

but it doesn’t work, I only find the last copied packages after the IDE start.

Answer 1

From luxsie:
How to merge several setup packages of Eclipse?

Whom this is for?
The ones that can not hold back their temper any longer when trying to install another Eclipse function package. Right the installation speed from some countries is too slow to bear, also the Equinox P2 always try to connect the Download.Eclipse.org. Much to damn.. when your Internet connection closed or reset all of a sudden and got all downloaded files broken. Also OSGi based Eclipse plugins is chaos — always have some conflict errors.
Oh that is another problem..

Do the following steps:

1 Download the Install Packages that you need from http://www.eclipse.org. Also please remember verify to see if that is correct package. I choosed J2EE with C/C++.

2 Unpack one package with uncompress softwares, such as 7-zip and WinRAR. unzip all the files to a directory you wanna install to. for example “D:\Eclipse\”.

3 open Configurations. Files “\configuration\org.eclipse.equinox.source\source.info” and “\configuration\org.eclipse.equinox.simpleconfigurator\bundles.info” in the installation directory is the ones that need to be merged. also you need “\configuration\org.eclipse.update\platform.xml”.

4 open the other packages and fetch their configuration files, and merge files.

to Bundles.info:
Open the bundle.info with any Functional Text Editor, copy all text begin from the line after “#version={Number}” and paste it to another. [{Number} means any Integer number.]

to Source.info:
Similiar with what you did with the bundle.info. If not modified, that line should be the 3rd line in the text file.

to Platform.xml:
Open the file, then find where “feature id=” starts just after the “site” node. Find the “/site” tag and copy all the text between them, paste to another file just before the “/site” tag.
[You can do the similiar also marked feature tags with artifacts.xml]

5 when merging i suggest you to make a new directory and when finished please remember copy the merged file to the one where should it be and overwrite. [I mean where it comes from]
Although not merge “platform.xml” will not cause any functional errors, it will make the About dialog with no button — to ugly yeah?
[= =|||]Ugly is caused by the artifacts.xml in the installation directory…

6 Open all the package, find “plugins” and “features” directories.now extract!
first extract the one you want most. I extracted JEE package.
then extract the other ones. I don’t see any problem whether Overwrite the ones or not.

7 do open a console window, and locale in the installation directory, and then execute “eclipse.exe”.

Well, somebody ask me why i paid no attention to the Artifacts.xml in the installation directory. That’s because Eclipse will never check the file. It seems to be when you want to update using zip files — however this way is blocked for lacking site.xml file now.

Then guys, wait a several minutes for eclipse to do some sorting and cleaning job for the merged configurations.. and install your plugins!

INFO: if you face some problems after install a new plugin and restart.. that is because you haven’t finish a complete artifacts.xml merging.
You may delete all the artifacts.xml ‘s header [document start to the “artifacts size = ‘{Number}'”] and its bottom [from “/artifacts” to document end]. just merge the left content. and make one file just contains the header and bottom, paste the merged one in.
Eh..maybe you can calculate the {Number}s’ sum and correct the one in the final document.
