Java Documentation from Vscode

Question

Hey I am using the Spring tool suite for Vscode It's working great but there is one thing I am missing like in other IDE's you can view the documentation for a specific Annotation or method. for example:

If I try to view the documentation for any annotation in intellij it shows the documentation properly, but if i try to do the same on vscode it shows up like this:

Hope this helps - https://stackoverflow.com/questions/47455756/how-to-trigger-documentation-popup-in-vscode — Piyush Pranjal, Sep 16 '22 at 17:18

You can enable the setting java.maven.downloadSources.

Then each time you opened a class file, if the source jar does not exist locally, the extension will trigger a download task for that source jar. After that, next time you open that class file, you can see the source.

This message says that VS Code couldn't find the JAR archive that contains source files for this class. These JARs usually are called XYZ-sources.jar. You need to download an archive like that manually or use the Maven plugin that can download it for you.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
        <execution>
            <id>src-dependencies</id>
            <phase>package</phase>
            <goals>
                <goal>sources</goal>
            </goals>
            <configuration>
                <silent>true</silent>
            </configuration>
        </execution>
    </executions>
</plugin>

Then, if you have downloaded JAR archive you need to press Right Mouse Button -> Attach Source.

ohh that's why. is there like any way to do this easily or do i have to attach source for all of the files manually? — Ishmeet Singh, Sep 17 '22 at 17:33
You should use approach mentioned by @Sheng Chen then. Make sure you have installed Java's extensions for VS Code. — Przemek Sulecki, Sep 18 '22 at 09:50
