trying to follow the main guide, but stuck at : Application "org.eclipse.jdt.ls.core.id1" could not be found in the registry

[survivant]

I'm looking for a sample / demo that call eclipse.jdt.ls from command line or better from maven. I want to to be able to apply the command "Organize imports" for my source code from the command line.

I cloned eclipse-jdt-ls repository and did this :

./mvnw clean verify -DskipTests=true -Pserver-distro I unpack the .gz file and launched it with this command line

java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044 -Declipse.application=org.eclipse.jdt.core.JavaIndexer -Dosgi.bundles.defaultStartLevel=4 -Declipse.product=org.eclipse.jdt.ls.core.product -Dlog.level=ALL -noverify -Xmx1G -jar ./plugins/org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar -configuration ./config_win -data ./path/to/data --add-modules=ALL-SYSTEM --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED I had to change "-Declipse.application=org.eclipse.jdt.ls.core.id1" for something else because the application id1 is not found.

but I don't know what to do from that.

@survivant I can't reproduce the issue.

I found the issue. I had JDK8 in my path . The problem is gone using jdk11.

[jiacai2050]

@survivant @snjeza Does this mean that jdt doesn't support jdk8? I meet the same issue, and problem resolved using jdk14

[jiacai2050]

• https://github.com/emacs-lsp/lsp-java/issues/249 Sad, I wonder is there any issue to support jdk8 ?

Java LS requires JDK11 to run. Your project can use JDK >= 1.5. See https://github.com/redhat-developer/vscode-java/wiki/JDK-Requirements

I have tried the same but with jdk 17.0.1 and had the same problem:

I have changed the order of the arguments as #1934 suggests but it still fails.

Edit:

Seems that powershell needs to receive all arguments in quotes (except -jar file) to work. After running it like that the command still not work but it writes the following log:

I got same error on Windows 10, but works well on Linux. Wired.

@Shane-XB-Qian jdt.ls now requires Java 17 to run (you can still compile Java 1.5...18 projects)

[Shane-XB-Qian]

jdt.ls now requires Java 17 to run

Oh My ............... ok. // maybe some years later, jdk 17 would be the default java package with linux distr. :-)

was the ok IF put a readme into released jdtls.tar.gz package? // and saying those requirement there? :-(

[fbricon]

@Shane-XB-Qian feel free to open a PR

[fbricon]

BTW, there's now a script to launch jdt.ls, that performs the requirement checks: https://github.com/eclipse/eclipse.jdt.ls/tree/master/org.eclipse.jdt.ls.product/scripts

[Shane-XB-Qian]

unluckly, I have no idea about those requirement with jdtls each version, but you are right, i found looks there was bin jdtls doing check and startup already. // so supposed that should be fine as long as people noticed that there.
