Adam,
I cannot help with Mac specificities, but on Ubuntu 20.04, after "sudo
apt install openjdk-17-jdk openjdk-17-jre", the GDAL Java bindings build
work just fine and the Java tests run with "ctest -R java" as well.

Hello,
My question is, is it possible to build the GDAL bindings for Java
17? I am trying to build GDAL with Java bindings for Java
temurin-17.jdk when prior I have been able to build and use the
bindings successfully for Java adoptopenjdk-8.jdk, using the exact
same build process. However when I run the equivalent build steps
with Java 17 I continue to receive this link error when implementing
the bindings:
*Native library load failed.*
*java.lang.UnsatisfiedLinkError: no gdalalljni in java.library.path:* ...
Exception in thread "main" java.lang.UnsatisfiedLinkError: 'void
org.gdal.gdal.gdalJNI.AllRegister()'
at org.gdal.gdal.gdalJNI.AllRegister(Native Method)
at org.gdal.gdal.gdal.AllRegister(gdal.java:664)
at Main.main(Main.java:14)
My system specs:
System Version: macOS 12.6.1 (21G217)
Kernel Version: Darwin 21.6.0
Boot Volume: Macintosh HD
Boot Mode: Normal
Secure Virtual Memory: Enabled
System Integrity Protection: Enabled
Time since boot: 15 days 20:17
Model Name: MacBook Pro
Model Identifier: MacBookPro18,3
Chip: Apple M1 Pro
When I run the build I see that the Java bindings are generated, the
.jar and libgdalalljni.dylib are created in /build/swig/java. Here are
the build commands used:
sudo arch -x86_64 /usr/local/homebrew/bin/cmake ..
-DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/bin
-DBUILD_JAVA_BINDINGS=ON -DBUILD_PYTHON_BINDINGS=OFF
-DCMAKE_OSX_ARCHITECTURES=x86_64 -DGDAL_USE_ZSTD=OFF
sudo arch -x86_64 /usr/local/homebrew/bin/cmake --build .
sudo arch -x86_64 /usr/local/homebrew/bin/cmake --build . --target install
Again, all of the above steps work when I am using JDK 8. So does
GDAL support Java bindings for JDK 17? Is there a way to resolve the
error *no gdalalljni in java.library.path? *Here are the path settings
in IntelliJ IDE:

*VM options:
-Djava.library.path=/Users/<username>/code/gdal-<version>/build/swig/java:$PATH$
Environment Vars:
PATH=/Users/<username>/code/gdal-<version>:/Users/<username>/code/gdal-<version>/build/swig/java:$PATH$
