Debug OpenJDK14 using CLion: failed to load the CMake project

I download the source code of OpenJDK14 and put them in \home\yuanfang\jdk14 and after running bash configure --disable-warnings-as-errors and make images, I build OpenJDK14 successfully, The newly built JDK is in home\yuanfang\jdk14\build\linux-x86_64-server-release\jdk. By the way, I am using Ubuntu 20.04 LTS.
Then I want to debug OpenJDK14 using CLion IDE. I was using CLion 2020.2 and I take the following steps:
After open CLion I choose Create New CMake Project from Sources and choose the directory of \home\yuanfang\jdk14, which is the root directory of the jdk project.
I alter the Run/Debug Configurations to make it look like this:
CLion create a CMakeLists.txt automatically but the file doesn't work, so after googling I find find the correct CMakeLists.txt here at https://github.com/ojdkbuild/ojdkbuild/blob/master/src/java-14-openjdk/CMakeLists.txt. I then rewrite the old CMakeLists.txt using the correct one.
I download the whole repository(that is, github.com/ojdkbuild/ojdkbuild), unzip it and put it into \home\yuanfang\jdk14.
It looks like as follow, the ojdkbuild-master is the newly added folder.
I reload the CMake project, but some CMake error occurs(as follow), why can't CLion find those files? javaI googled but can't find any effective solution. Is there anything I can do or refer to? Thanks in advance.

step: check out this projecdt :https://github.com/ojdkbuild/ojdkbuild.git
step: put the source code of OpenJDK14 in ojdkbuild/src/
step: copy reousrces directory and CMakelists.txt to OpenJDK14
step： recomile openjdk and import project to CLin

CERTIFICATE_VERIFY_FAILED when trying to build java-cef

I'm trying to build java-cef on ubuntu following instructions from https://bitbucket.org/chromiumembedded/java-cef/wiki/BranchesAndBuilding.
At cmake step
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..
i get
-- Downloading clang-format from Google Storage...
Failed to fetch file gs://chromium-clang-format/942fc8b1789144b8071d3fc03ff0fcbe1cf81ac8 for tools/buildtools/linux64/clang-format.

]
Terminal indicates that I'm using Python 2.7.15+.
How can i make it work? Many thanks.

In the folder where it has created the build jcef/src/tools/buildtools/download_from_google_storage.py change the version parameter of gsutil to a recent version, like 4.39. If you don't find specified file use a tool like find.

cannot find org.neo4j.batchimport

I am continuing to have trouble with the import.bat file for the Neo4j batch importer. I started a new thread as the original problem was resolved.
from the command prompt I run
import.bat test.db sample\nodes.csv sample\rels.csv
With some variations on the path listing for the files, including absolute paths. I continue to get the following error message
The system cannot find the path specified.
Error: Could not find or load main class org.neo4j.batchimport.Importer
I also tried running import.sh from Cygwin and in my Debian VM but keep getting the error
Error: Could not find or load main class org.neo4j.batchimport.Importer
What am I doing wrong?

Please download the zip-file, not the github clone.
This is a pre-build binary as outlined in the readme, that doesn't require that you have to have maven installed to build it.

Monodevelop + IKVM : Java build error ("Error: invalid path: *.class")

I am using the monodevelop Java plugin to compile a simple (hello world) Java project. The project is created fine, but when I try to build it I get the following error:
"Error: invalid path: *.class"
The command that triggers the error is as follows:
ikvmc -recurse:*.class -assembly:jTest -target:exe -debug -srcpath:/home/bob/src/jTest/jTest -r:mscorlib
Any idea what's going wrong, and how to fix this?
P.s. Please do not say "Mono is not for Java. Use (insert different Java IDE here) instead"
Thank you!

I think .\*.class sould be run better. There must at minimum one slash in the path.

Ghost4J. java.lang.UnsatisfiedLinkError: Unable to load library 'gsdll64'

I included Ghost4J 0.45 into my project using Maven and installed Ghostscript into C:\Program Files\gs\gs9.06.
But I still get an error java.lang.UnsatisfiedLinkError: Unable to load library 'gsdll64'.
I added into PATH env variable directory where located 'gsdll64.dll' (i.e. C:\Program Files\gs\gs9.06). Also tried launch application using -Djava.library.path=/path/to/dir.
But I alwways get UnsatisfiedLinkError (but when I launch using JVM argument -Djava.library.path I get ClassNotFound exception (Eclipse can't find Main class, but I manually point Eclipse to Main class when I laucnh my app))/

Does it work if you copy gsdll64 to your working directory? :-)

if u want to use a system property
-Djna.library.path=/path/to/dir should be used instead of -Djava.library.path=/path/to/dir
