2.0.15 asking for java installation - SOLVED (sort of)

[josephbottinger]

I just installed the new 2.0.15 MD. On startup, it says that it wants me to install a JVM.

I have *plenty* of JVMs. javac -version on the terminal works *perfectly*. I can switch JVMs all you like, actually. However, I don't know that it's using the *right* JVM, but the problem is that I have no visibility into this.

I'm using SDKMan; could MD use JAVA_HOME instead of ... whatever it's using, to find the JVM? Pretty please?

Joseph,

Have you tried setting the jdk location explicitly in the preferences?

Yes, I have. I tried the location of the JVM (the value of JAVA_HOME, such that "$JAVA_HOME/bin/java -version" gives me the version) and the directory that contains the "java" executable itself; after setting it, I exited the Module Designer and restarted; same results. The log file shows it requesting the java version but not the command line it's trying to run.

Hi Joseph.

If there's no custom JDK path in the preferences, the module designer will just rely on the OS to resolve the path to java, javac, etc.

If you specify a custom path, it should use that. However, there was a bug with retrieving the custom path when checking Java versions at startup. It'll be fixed in the next release.

[josephbottinger]

Well, if I have any request here, it would be that you dump the locations you're checking into the system logs, so I can at least see what it's TRYING to do, too.

I just installed 2.0.17 and it's STILL not loading java properly from my specified location. The log shows nothing relevant that tells me why. It has the preference set to point to a Java 11 SDK (installed via SDKMan, so it's openJDK) and it won't build.

[josephbottinger]

STILL having the problem. Installed 2.0.17 this morning. On initial startup, I see the "To use the "java" command-line tool..." as shown in the 08.36.39 image attached. (When I tried to place multiple images inline the post got screwed up somehow and I couldn't figure out how to fix it.)

Selecting "More Info" goes to: https://get.adobe.com/flashplayer/ ... which... uh... no.

I have my preferences set to a working JVM, as shown in the other attached screenshot. This is a JVM I use *all the time* for work; it's not a "I tried to install the java and this is what sort of happened, does it work?" installation.

That is, however, located in ~.sdkman; the way I located it is via a symlink in the tool, and VMD is resolving it to the actual directory for the preferences. I've tried setting it specifically to use the symlink, but it goes back to the actual filesystem location.

The logs show me nothing that the screen doesn't. I can't attach the log file here (invalid attachment extension) so here's the relevant bit of the log as far as I can tell:

Note that

Code: Select all

/usr/libexec/java_home

reports that no JVM is installed; I've filed a bug against SDKMan because of this (because it's the "default place" to look for a JVM on OSX.) However, I *specifically* set the JVM location in the preferences as shown in the preferences screenshot, so the libexec issue shouldn't be a factor here.

[josephbottinger]

Crikey. It only accepted the one screenshot. Here's the other:

Okay, I worked through it. It's not.. .difficult, just annoying.

The answer is to install an AdoptOpenJDK build (or similar) to the OS level, as opposed to at the user level; you can do so through a JVM downloaded from https://adoptopenjdk.net/releases.html? ... nt=hotspot . This installed a proper system-level JVM, and /usr/libexec/javahome reports it as a JVM; VMD loaded it fine (despite still having the custom JVM location set, which I think is still a bug) and stopped reporting an error.

worked for me thank you
