Qute LS freezes when LSP client doesn't support workspace/didChangeWatchedFiles and have no templates folder

[angelozerr]

When LSP client cannot support workspace/didChangeWatchedFiles, the Qute LS uses FileSystemWatcher and if the project have no src/main/resources/templates, it blocks the language server

quarkus-ls/qute.ls/com.redhat.qute.ls/src/main/java/com/redhat/qute/project/WatchDir.java

Line 102 in 2be29a3

if (Files.notExists(dir)) {

We need to poll the existing of src/main/resources/templates in Thread.

Please note that:

• in vscode we have not the problem because vscode supports workspace/didChangeWatchedFiles
• in IJ I'm implementing workspace/didChangeWatchedFiles fix: Set project as workspace folder intellij-quarkus#1163
• in Eclipse IDE I created the issue to support workspace/didChangeWatchedFiles Support for workspace/didChangeWatchedFiles eclipse/lsp4e#807 //cc @sbouchet
