I also try another Eclipse eclipse-cpp-neon-3-linux-gtk-x86_64.tar.gz eclipse-cpp-photon-R-linux-gtk-x86_64.tar.gz eclipse-cpp-2019-03-R-linux-gtk-x86_64.tar.gz with the same Problem
你怎么老盯着旧版本，4.10，4.11，4.12，4.13，4.14，4.15，4.16试了吗，人家会去改旧版本吗，不存在的。
This is a deadlock caused by CDT: - CDTCommonProjectWizard$1.run(CDTCommonProjectWizard.java:242) tries to run something synchronous on the UI thread. - CDTCommonProjectWizard.invokeRunnable(CDTCommonProjectWizard.java:177) is blocking the UI with a modal dialog Looks a lot like Bug 321696.

Bug 321696 (which was a dup of Bug 321640 which is marked as worksforme) was apparently resolved by Bug 262032 in the platform's Deadlock Detector. While CDT is exposing a problem, the main thread has a modal dialog open, but the dialog is back in Display.readAndDispatch so syncexecs from other threads should be working fine. AFAICT the bug here is the modal context thread should be getting the lock to do the syncexec but is failing to. @Shuai, do you have anything in your workspace/.metadata/.log file? BTW the Gtk-WARNING and Gtk-CRITICAL can probably be ignored in this context. When using the Java version, do you also get a lockup? If so, can you provide the jstack for that too?

When using the Java version, do you also get a lockup? If so, can > you provide the jstack for that too? YES, I also get a lockup. the jstack named jstack_eclipse-java-oxygen-3a-linux-gtk-x86_64.txt. The different from CDT is that I kill the Eclipse-PID and check the background the project folder is created. But the Wizard-UI cannot finish.
When Eclipse is stuck, do you see the modal dialog? That is, there should be a small dialog on top of your Eclipse IDE. This one should be able to gain focus. What do you see? What makes you say that Eclipse is stuck? Just asking to get better insights into your problem.
Does the small dialog mean "Create a Java Project" dialog? If so, it always showing up on eclipse doesn't disappear. I can not do anything with eclipse as this time. I suspect the problem is caused by environmental variables. Do you have any suggestions on this？ Thanks very much.(In reply to Rolf Theunissen from comment #12) > When Eclipse is stuck, do you see the modal dialog?

I can not do anything with eclipse as this time. I suspect the problem is caused by environmental variables.(Such as PATH or LD_LIBRARY_PATH) Do you have any suggestions on this？ Thanks very much.
