SDKMAN! does not work with Eclipse.app or SpringToolSuite4.app (on Mac)

问题


This is a similar issue to: Eclipse can't find jdk installed with sdkman

I am still facing the issue on Mac (macos-mojave)

Both of my

/usr/bin/java
/usr/bin/javac 

are pointing to

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/javac

respectively.

SDKMAN! does install the proper java and javac for the SDKMAN!'s default Java version.

Thus, I do have proper java and javac:

% java -version
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.3+7)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.3+7, mixed mode)

% javac -version
javac 11.0.3

However, I do not have any Java versions installed in:

ls -la /Library/Java/JavaVirtualMachines 
total 0
drwxr-xr-x  2 root  wheel   64 Jun 19 10:06 .
drwxr-xr-x  4 root  wheel  128 Apr 16 06:16 ..

EDIT:

I also tried updating the JVM reference in /Applications/SpringToolSuite4.app/Contents/Eclipse/SpringToolSuite4.ini (comparable to Eclipse.ini):

-vm
/Users/johndoe/.sdkman/candidates/java/current/bin/java
-startup
../Eclipse/plugins/org.eclipse.equinox.launcher_1.5.300.v20190213-1655.jar
--launcher.library
../Eclipse/plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.1000.v20190125-2016
-product
org.springframework.boot.ide.branding.sts4
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m
-XX:+UseG1GC
-XX:+UseStringDeduplication
--add-modules=ALL-SYSTEM
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Xdock:icon=../Resources/sts4.icns

I do get a splash screen for STS, but it still reports no JVMs installed (see screenshots)

And it seems both Eclipse.app and SpringToolSuite4.app require proper JDK installed traditionally, not using SDKMAN!

I really don't want to install another JDK besides SDKMAN!

Anyone got this to work?

Thanks!


回答1:


If the Eclipse launcher cannot find a suitable JVM to run on (which I am assuming is the problem here), you can usually work around this by pointing the 'eclipse.ini' (or 'STS.ini' as the case may be) to the JVM of your choice.

To do this, open the .ini file in a text editor and add two lines at the front of the file. Something like this:

-vm
/usr/lib/jvm/jdk-1.8.0/bin/java
... the rest of the file unchanged...

Note it is important that:

1) these lines are the very first in the file

2) they are on two separate lines (don't try to put both -vm and path of the jvm executable on a single line, it doesn't work).




回答2:


I faced this problem on macOS Sierra while trying to use OpenJDK 11.0.2 installed by SDKMAN! in conjunction with Eclipse 2019-06. No other SDKs installed.

macOS consistently seems to refuse launching Eclipse.app for almost all combinations of -vm parameters I supplied in Info.plist and eclipse.ini, except for links to /System/Library/.

Here is my working setup:

  1. I did an sdk default java 11.0.2-open rather than just sdk use. I made sure SDKMAN! symlinked JDK command binaries properly into the /System/Library path:
lrwxr-xr-x  1 root  wheel  75  1 Mai  2017 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

Although the symlink destination is not a link anymore, it is the binary that SDKMAN! deployed there. Check it with the -version.

  1. I made sure no <string>-vm</string> parameter is present in Info.plist. All commented out.

  2. My -vm arg in eclipse.ini is:

-vm
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

As stated previously, make sure this statement appears before -vmargs.

This finally allows me to launch a recent Eclipse by double-clicking in the Finder or launching the eclipse binary directly. Hope this applies to STS as well.

Good luck.
