VSCode Java isn't running the latest code

[ZZYSonny]

When I changed something in the code and run it, VSCode is running the old version and give me the old response. When I run the code for the second time without changing it, it runs the new one.

Environment

• Operating System: Mac 10.13.3
• JDK version:9.0.4
• Visual Studio Code version:1.19.3
• Java extension version:0.17.0
• Java Debugger extension version:0.5.0

Steps To Reproduce

1. Open any code, run once (First output in the photo)
2. Quickly change part of code, run immediately, check the response (Second output in the photo)
3. Run the code without changing any thing, check the response (Third output in the photo)

Current Result

Expected Result

Response at 2 should be same with 3

Additional Informations

If not running immediately, it will run the latest code. Probably need some delay before running?

Interesting finding, we will wait for the signal of build complete before launching, can you share your launch.json and tasks.json(if you have) in your .vscode folder?

[ZZYSonny]

Java Language Service plugin automatically do the compile so I think there is no need to have a task.json file to build. And I remember at early version of debug plugin, it waits for the compile.

I cannot reproduce it no matter how fast I change my code, would you please upgrade to the latest version and try to reproduce it:

Language support for Java:0.20.0
Java Debugger extension version:0.6.0

[ZZYSonny]

Still reproducible on latest version (Language support 0.20.0, Debugger 0.6.0, VSCode 1.20.1)

It is more likely to happen when you immediately press F5 to run the code after making one change. (Well probably that's what I usually do when I code) And it is also more likely to happen when the code is more complex.

I've made a gif to show. It happens both on Windows and Mac. And it is easier for me to record it on Windows.

Based on your gif, it is because you don't save after edit, it should be a bug but is trivial and we will fix it later. I will create a new bug of this.

Test passed.

Vscode: 1.21.1
Java debug build: andy private build/39
