            Unable to create Z shell alias to "activate" Java 8 (OpenJDK) on macOS
            Asked 2022-Jan-02 at 19:04

            I have followed the advice given in this answer to create aliases which allow me to quickly switch between JVM versions on macOS. And I have cross-checked with this article, which suggests a similar solution. This works well for Java 15, but not for Java 8. See details below.

            Oh, my goodness… The answer was in front of my nose all along:

            "Unrecognized option: --version"

            With Java 8, the command --version is invalid. Instead, I had to use -version. Newer versions of Java support both commands (with one or two -), which threw me off.

            which java is often used to find the exact executable you are calling when you type in java.

            Keep in mind that when you type in the command java your JAVA_HOME setting is not used. Rather, the operating system PATH setting is used. If you have an older copy of java "before" the one you want to use on the path, then that's what the operating system will give you. To fix a problem like this, you need to alter your path such that the directory of your desired java version comes before any other java versions.

            I do see that you checked your PATH setting, but I think you didn't know what to check, because you only listed directories. In those directories, a java executable exists. If the old executable comes in a directory earlier in the path, that's the version of java you will get when running it from the command line, regardless of any other settings.

            Now, it is still important to have the JAVA_HOME set correctly, because when various Java tools want to discover items, thy might read JAVA_HOME (and if it is wrong, get directed to a non-matching JVM).



            Netbeans 12.5 can't install Java ME plugin
            Asked 2021-Nov-23 at 08:38

            Below is what I'm using,

            • OS: macOS Big Sur
            • NetBeans: 12.5
            • Java: 7 / 8 / 17

            I'm trying to install Java Me plugin

            Upon installation, i kept getting this

            I have tried using java 7, 8 and 17 (I'm using jenv to control java version).. Nothing works.. Could anyone please help?

            EDIT: Below is the log i get when i trying to install (using jdk17, I also checked the firewall is off)

            The OP's error message "The plugin install found problem timeout of loading Java ME Web Service Clients" is misleading, since it suggests that there may be a network issue. However, the FileNotFoundException in the NetBeans log file shows that the real cause is that the plugin installer is failing because it can't locate the file unpack200.exe to unpack the downloaded plugins.

            This issue arises if NetBeans is running on JDK 14 or greater, since unpack200.exe was removed in that release. See JEP 367: Remove the Pack200 Tools and API for details.

            A workaround in the past has been to temporarily run NetBeans with an earlier JDK which contained unpack200.exe, typically JDK 8 or JDK 11. Then, once the plugins had been successfully installed, just revert to using your JDK >= 14. That approach is documented in great detail here. Most of the individual steps in that answer remain valid, but there is no longer any need to revert to running NetBeans on a JDK < 14 because there is a simpler approach available.

            When running NetBeans 12.5 on a JDK >= 14, the plugin installer now detects that unpack200.exe is missing after downloading the plugins, and invites you to provide an instance of it:

            Clicking the Choose Unpack200... button in the lower left of that screen opens the following dialog:

            Navigate to any instance of unpack200.exe on your machine. It will reside in the bin directory for any JDK release < 14. Once the plugin installer has located an instance of unpack200.exe it can convert the downloaded plugins into jar files to complete the plugin installation process.


            • Although this question is about the Java ME plugins, the same approach applies when running NetBeans on a JDK >= 14, and installing any plugin that uses the Pack200/Unpack200 APIs.

            • NetBeans asking for a location of unpack200.exe only happens once. Thereafter it uses the location you provided initially by default.



            How do I get rid of jenv in Ubuntu?
            Asked 2021-Nov-22 at 22:25

            I think I need to undo some commands I entered when trying to get jenv on my ubuntu instance and I am not sure how to do that.

            Here's what I did:

            brew install jenv

            echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile

            echo 'eval "$(jenv init -)"' >> ~/.bash_profile

            jenv add /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

            That last command gave me an error, and I ended up restarting my shell for whatever reason. Since then, all text is white (used to be multicolored), brew no longer works, and it says this:

            Command 'jenv' not found, did you mean:

            command 'env' from deb coreutils (8.30-3ubuntu2)

            Try: sudo apt install

            Couldn't find an alternative telinit implementation to spawn. user@DESKTOP-FG073RE:/mnt/c/Users/user$

            I fear I messed up the PATH but I am not sure how to fix it. I tried to run the same command again but omitting the 'j' but that did nothing. Can't seem to find anything about this error online either. I also tried to uninstall jenv but that also did nothing.

            I went into the ~/.bash_profile I made and deleted everything from it
