node-gyp rebuild fails. fatal error: 'jni_md.h' file not found on OSX 10.11.5

[gnizhak]

We use node-tika for our project and it's only dependency is node-java. Last week npm install started failing to an error during node-gyp rebuild

as you can see from the error message I use jenv to manage my java version but the issue appears on both java 1.7 and 1.8. My JAVA_HOME is thus set /Users/gnizhak/.jenv/versions/1.7 or 1.8 Both JDK installations are Oracle Java and I do not have java 1.6 installed.

xcode-select version 2343 and xcode version 7.3.1 (so gcc says Apple LLVM 7.3.0)

I'm not really in on how the java includes folder is setup on Oracle Java I tried to do some digging and found that /Library/Java/JavaVirtualMachines/{jdk_version}/Contents/Home/include does not contain jni_md.h directly but instead has a subfolder /Library/Java/JavaVirtualMachines/{jdk_version}/Contents/Home/include/darwin where the jni_md.h header file resides.

This issue did not appear in May, but I was away from the project most of June and July so I cannot tell which update may have caused this issue.

I checked out the Info.plist capabilities section referenced in https://github.com/joeferner/node-java/issues/90#issuecomment-45613235 and found that 1.8 already had the capability there and adding that to 1.7 did not resolve the issue.

My colleague with OSX 10.10.5 with xcode-select 2339/xcode 7.2.1 had no such issue.

I'm having the same issue. Also using jenv. Is it possible it's a problem with jenv?

I am having the same issue when I tried to use the "jabba" java environment manager. Any updates on this issue?

[cksachdev]

@gnizhak Have you figured out a solution for this? I have the same issue, managing java versions using jabba and when installing it fails. cc: @owendall @tandrewnichols

[gnizhak]

I ended up giving up on jenv and installing different sdks independently. So it has to be the way the jenv/jabba handles the paths on the dependencies.

This is an issue I think for all conformant non-Oracle JDKs at least since 11 on macOS, because jni_md.h is located in /include/darwin

[cdolek]

Mac OS Catalina 10.15.16, using jenv.

I noticed that $JAVA_HOME was not set. Disabling and enabling jenv plugins fixed this.

Per @doctorpangloss's comment copied the file to parent dir:

cp /Users/_username_/.jenv/versions/openjdk64-1.8.0.265/include/darwin/jni_md.h ../

npm install java - voila!
