Requirements
For running the binary version:
- Windows, macOS, or Linux, on a x86_64 CPU
- We do not currently support running on Linux installations without
libc
present
- We do not currently support running on Linux installations without
- Java is not required for this version
- The binary is automatically downloaded by vscode-xml if it is needed, with no additional action required on the part of the user.
For running the Java version (required if you want to run extensions to the base XML features):
- Java JDK (or JRE) 8 or more recent
- Ensure Java path is set in either:
xml.java.home
in VSCode preferencesjava.home
in VSCode preferences- Environment variable
JAVA_HOME
orJDK_HOME
- Note: The path should end at the parent folder that contains the
bin
folder. Example Path:/usr/lib/jvm/java-1.8.0
ifbin
exists at/usr/lib/jvm/java-1.8.0/bin
. - Note: If the path is not set, the extension will attempt to find the path to the JDK or JRE.
See how to set java home for more information how this extension searches for Java.
Supported VS Code settings
The following settings are supported:
xml.java.home
: Specifies the folder path to the JDK (8 or more recent) used to launch the XML Language Server if the Java server is being run. If not set, falls back to either thejava.home
preference or theJAVA_HOME
orJDK_HOME
environment variables.xml.server.vmargs
: Specifies extra VM arguments used to launch the XML Language Server. Eg. use-Xmx1G -XX:+UseG1GC -XX:+UseStringDeduplication
