Visual Studio Code 中的 java 代码无法识别 Clojure 项目中的命名空间

Question

I need some Java code to work with in Clojure project. Following this page to learn how to mix Clojure/Java in Leiningen. The project was running smoothly, the result is same as expected. However, when I open the project in vscode, the namespace "myproject.records.time" in Lexer.java; it cannot be recognized in vscode but it can be recognized in command line "lein do run, clean". I have already execute the command "java: clean language server workspace" in vscode, but the errors are still exist. Please comment how to fix this error in vscode?

command line "lein do run, clean". Working successfully

=> #'myproject.main/-main
({:type :error, :value "4"}
 {:type :error, :value "3"}
 {:type :error, :value "2"}
 {:type :error, :value "1"}
 {:type :error, :value "0"})
=> nil

the namespace "myproject.records.time" cannot be recognized in Lexer.java with vscode

Answer 1

You need to add Clojure.jar to current Project.

Reference: leiningen - how to add dependencies for local jars?

Answer 2

Summarized procedures to solve the errors.

1. Download the latest stable release of Clojure. Unzip it and find the file clojure-xyzjar. Copy this file into your project somewhere (eg. ./lib/clojure-1.10.3.jar ). # thanks Molly Wang

2. Put the following statement into the project.clj .

   :aot [myproject.records]

3. Execute lein uberjar in the project directory, a jar file will be generated under the directory ./target/uberjar

   eg ./target/uberjar/XXX-0.1.0-SNAPSHOT.jar

4. In left hand side of vscode, there is a tab named Referenced Libraries , add these two files clojure-1.10.3.jar and XXX-0.1.0-SNAPSHOT.jar with + (at the right hand side of the tab Referenced Libraries ); respectively.
