Hello, I’m trying to install MyEclipse in an Ubuntu 20.04 and I’m getting an error “java.lang.NoSuchFieldException: isUTF8”
I don’t know exactly what i need to do to solve it.

Can you help me?

I attach the log that the installer has created.

Thanks

Ruben,

Sorry that you are seeing this issue.

Is Java 14 installed at system level? We have a known problem with the installer failing on some machines when Java 14 installed at system level. For some reason, the installer is falling back on the system installation of JDK 14 and failing due to deprecated packages.

Can you try running the installer with a -nojre flag? This is a flag that should disable the system JRE detection and force the inbuilt JRE to be used. To use this, open a command prompt, go to the folder containing the installer and run -nojre.

Please let us know if this fixes the installation problem for you.

Apologies for inconvenience caused.

Yes, I have Java 14 installed.
I’ve tried with the -jre flag and I have the same error.

I’ve also tried to install java 11 (and swapped with “sudo update-alternatives –config java”), but now, the installer crashes on the first “next” click.
In this case there’s no error log created

Ruben,

Can you please clarify if you tried with -jre or -nojre?
Please share with us the installer log file once again if it fails with -nojre. Also share with us the command you used to run the installer from the command prompt.

I’ve tried both, with -jre and with -nojre
I’m getting the same error in both cases.

My commands:
chmod +x myeclipse-2020.9.16a-offline-installer-linux.run
./myeclipse-2020.9.16a-offline-installer-linux.run -nojre

Ruben,

Looks like the -nojre isn’t working for Ubuntu 20. Can you please try running the installer with -vm arg and pointing to a Java installation <14?
From the command prompt, please run it as per this format : <path-to-me-installer.exe> -vm "<path-to-javaw.exe>"

Apologies for inconvenience caused. Please let us know how this works for you.

I’ve tried these two command lines:

1) ./myeclipse-2020.9.16a-offline-installer-linux.run -vm /usr/lib/jvm/java-11-openjdk-amd64/
2) ./myeclipse-2020.9.16a-offline-installer-linux.run -vm /usr/lib/jvm/java-14-openjdk-amd64/

in 1)
I’m having the same issue that when i try installing with JAVA 11, the installer crashes just after the first “next”, without any log

in 2)
I’m having the same issue that when i try installing with JAVA 14, the installation stops after a while

[support-swapna]

Ruben,

You should point to the javaw.exe path which is under the bin folder of the Java installation directory.
Example : ./myeclipse-2020.9.16a-offline-installer-linux.run -vm "<java installation directory>\bin\javaw.exe"

Hello again.

There’s no “.exe” files in Ubuntu (this is a Linux OS).

And there’s no “javaw” file in the JAVA_INSTALLATION/bin folder.

All the files in that folder are:

jaotc, java, javap, jdeprscan, jhsdb, jjs, jmod, jshell, jstatd, rmic, serialver, jar, javac, jcmd, jdeps, jimage, jlink, jps, jstack, keytool, rmid, unpack200, jarsigner, javadoc, jdb, jfr, jinfo, jmap, jrunscript, jstat, pack200, rmiregistry

[support-swapna]

Ruben,

Can you use java instead of javaw and check if it works?

1) ./myeclipse-2020.9.16a-offline-installer-linux.run -vm /usr/lib/jvm/java-11-openjdk-amd64/bin/java
2) ./myeclipse-2020.9.16a-offline-installer-linux.run -vm /usr/lib/jvm/java-14-openjdk-amd64/bin/java

Same behaviour as before

Ruben,

Sorry that the issue persists. We did try with Java 11 and it worked for us. But can you please check with Java 8 or 9?

[ruben-in-primis]

It has worked with JAVA 8, I’ve not tried with JAVA 9.

Does it means that i have to continue with JAVA 8 instead of JAVA 14 or 11 to use MyEclipse?

[support-swapna]

Ruben,

Glad that the installation is successful. The issue is with the installer having trouble running with Java 14. We will fix it for the next release.
Once MyEclipse is installed, it will run with the bundled Java 14.

Hope this helps. Please let us know if you see any issues.
