Could not write lock info file

[jonahgraham]

Let's make sure issue is not already fixed in latest builds first.

• I verified I can reproduce this issue against latest Integration Build of Eclipse SDK

Starting Eclipse on Windows now has an exception about writing lock file (see log below). The IDE starts properly on quick inspection, but not sure if there are other side effects.

Steps to reproduce

From a fresh installation and clean workspace:

• Load current source code in SDK
• Launch a development Eclipse instance

Here is some relevant log output

From <workspace>/.metadata/.log

Tested under this environment:

• OS & version: Windows 11
• Eclipse IDE/Platform version (as shown in Help > About): 2024-12 (4.34) I20241018-0730
• Java version: Eclipse Adoptium jdk-21.0.4.7-hotspot

Community

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.

Looking briefly at the code and error I think the handling of paths in the new code from #2347 is different from the older code. The newer code is using java.nio classes like Path and the old code relied on java.io.File for path handling. On Linux this seems to make little difference, but on Windows there seems to be a problem in how it is handled?

I saw this first in development environment, but running just a freshly downloaded SDK shows the problem too:

Fortunately it is not a regression but just a bug in a new functionality, so there shouldn't be any other side effects except error log entry. awe will fix it ASAP next week. Thanks for reportikg!

[HannesWell]

Noticed this as well and already started to prepare a fix. It's now in

• Fix lock path computation on Windows and minor simplifications #2426

Thanks, I was also checking this.
