Re: [m2e-dev] Setup environment in relation to https://github.com/eclips

[Alexandros Karypidis <akarypid@xxxxxxxx>]

So, I repeated the same in Linux and it works:

$ mvn --version

Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)

Maven home: /home/user/.sdkman/candidates/maven/current

Java version: 17.0.2, vendor: Eclipse Adoptium, runtime: /home/user/.sdkman/candidates/java/17.0.2-tem

Default locale: en_GB, platform encoding: UTF-8

OS name: "linux", version: "5.18.5-arch1-1", arch: "amd64", family: "unix"

The problem is therefore specific to Windows.

I will move this to github discussions for resolution: https://github.com/eclipse-m2e/m2e-core/discussions/822

Hello,

I'm having the same issue. So, I am using the Eclipse PDE created by https://www.eclipse.org/setups/installer/?url=""> though I do not think that matters as I am following the "Set up manually" section of https://github.com/eclipse-m2e/m2e-core/blob/master/CONTRIBUTING.md.

From command-line I cloned a fresh repo:

> git clone git@xxxxxxxxxx:eclipse-m2e/m2e-core.git

Cloning into 'm2e-core'...

Enter passphrase for key '/c/Users/user/.ssh/id_github':

Then I run the command to manually generate the missing file:

> cd .\m2e-core\

> mvn generate-sources -f m2e-maven-runtime -Pgenerate-osgi-metadata -Dtycho.mode=maven

[WARNING] org.eclipse.tycho.extras:tycho-pomless build extension will be replaced in a future version of Tycho by the new org.eclipse.tycho:tycho-build extension.

[WARNING] You can simply change your .mvn/extensions.xml to reference the new extension right now:

[WARNING]    <version>2.7.2</version>

At this point I have not used the Eclipse PDE, just command-line git/maven/java:

> git --version

git version 2.36.1.windows.1

> mvn --version

Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)

Maven home: C:\Users\user\scoop\apps\maven\current

Java version: 17.0.3, vendor: Eclipse Adoptium, runtime: C:\Users\user\scoop\apps\temurin-lts-jdk\current

Default locale: en_GB, platform encoding: Cp1252

OS name: "windows 11", version: "10.0", arch: "amd64", family: "windows"

Did you ever get to the bottom of this? How can I generate the missing file(s)?

That file is supposed to be generated by the command-line you run.
