Hi,
I try to install Eclipse Oxygen on my laptop with Windows 7 x64 but my company use a proxy to permit the access to internet. I have this rights.
I follow the steps reported in the follow link https://www.eclipse.org/downloads/eclipse-packages/?show_instructions=TRUE
but install eclipse IDE but generate a lot of error messages linked to the proxy authorization and also when I create a project return problem about Maven with proxy.

Someone can help me and explain exactly what I need to do to configure correctly the installer and after IDE to create the project in the correct way.

Thanks in advance for any help

Marco

It's hard to know in general about proxy settings because it depends so much on your company's proxy details. Both the installer's menu (in the upper right) and in Eclipse's Window -> Preferences -> General Network Connections give you the ability to control how network proxies are configured. The settings you change in the installer will be copied to the installation... But I can't know what's right in your company...

Hi,

I have a similar problem.
Could you tell me please, which rules or exclusions do we have to configure, in order to install eclipse?

This is the error detail:

I don't know what an "exclusion" rule is... Are you behind a proxy that "excludes" some URLs? In general, don't exclude anything from download.eclipse.org...

Which URLs are accessed will depend on which version of the product you are installing, and these locations (p2 repositories) can have references to other p2 repositories. For example, https://download.eclipse.org/oomph/updates/milestone/latest/compositeContent.jar contains compositeContent.xml which currently looks like this:
<?xml version='1.0' encoding='UTF-8'?>
<?compositeMetadataRepository version='1.0.0'?>
<repository name='Oomph Latest Milestone' type='org.eclipse.equinox.internal.p2.metadata.repository.CompositeMetadataRepository' version='1.0.0'>
  <properties size='2'>
    <property name='p2.timestamp' value='1555221281770'/>
    <property name='p2.compressed' value='false'/>
  </properties>
  <children size='1'>
    <child location='../../../drops/milestone/S20190414-014413-1.13.0-M1'/>
  </children>
</repository>
This changes when there is a new milestone build, though always to something under https://download.eclipse.org/oomph/drops/

In any case, you already see in the log which "top-level" p2 repository URLs are being accessed, and you can browse those URLs in the browser to see their contents.

Hi

Finally we could access to The different urls, but The error changed.
Do you have any idea about this?

Perhaps previous attempts have left garbage in your bundle pool so you could try to repair it:

https://www.eclipse.org/forums/index.php/m/1780180/?srch=repair+bundle+pool#msg_1780180

If you have no successful installations that are using your bundle pool, you could delete the entire C:\Users\cararroy\.p2 folder to start from scratch; note doing this will destroy any installations that use this bundle pool so don't make a habit of it.

This sounds like the same type of issue as this thread:

https://www.eclipse.org/forums/index.php?t=msg&th=1096677&goto=1799997&#msg_1799997

I.e., it's an issue with the certificates known/accepted by the JVM that you are using. Often installing and using a newer version of Java will solve the problem. It's also possible to add the certificate to the certificate store but that's quite a complicate procedure:
