Clojure debugger doesn't stop on breakpoint

[zeafynx]

I'm using: OS X 10.11.6 Intellij IDEA 2017.2.2 Cursive 1.6.1-2017.2

I would like to debug the following code "test.clj". The breakpoint is at the line of "print".

(defn foo []
  (print "hello"))

(foo)

I tried both methods below to debug:

1. Click "Run" -> "Debug 'test'". Here is the output:

Connected to the target VM, address: '127.0.0.1:51992', transport: 'socket'
hello
Disconnected from the target VM, address: '127.0.0.1:51992', transport: 'socket'

Process finished with exit code 0

The program doesn't stop at the breakpoint.

2. Run the REPL in debug mode. The program doesn't stop.

Do I miss anything when using Clojure debugger?

I am experiencing the same problem. I must add that before the debug console shows any info, the whole IDE is frozen for a few seconds

Workaround if anyone finds this issue via search as I did

You should use JDK 8 and not JDK 9

After trying older versions of this plugin without success, I tried older versions of the JDK and it seems to do the trick, my exact versions:

• not working Zulu Java 9 OpenJDK 9.0.0
• working Zulu Java 8 OpenJDK 8u144

[cursive-ide]

Hmm, that's worrying, thanks for the report. @zeafynx Are you using JDK9 too?

[zeafynx]

@cursive-ide No, here is my JDK info:

$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

Yes, JDK 9.0.1 is a problem as well. Downgrading to JDK 8u152 on OSX solved the issue.

Hi, I can confirm this JDK 9 issue on Windows as well. Downgrade to JDK 8u152 worked. Message when hovering over the breakpoint was: "breakpoint doesn't belong to any class"

IDEA 2017.3.1

same problem OS X 10.13.6 Intellij IDEA 2018.2.2 Cursive 1.7.0-2018.2

Hi Everyone, I'm having exactly the same issue ... Meaning it doesn't stop on breakpoints when I launch the debugger.

OSX 10.14.6 Intellij IDEA 2019.3.2 Cursive 1.9.1-eap2-2019.3

I tried JAVA 8 and JAVA 11 ... Same issue .. Any idea ?

When I go into the "View Breakpoints" window .. I can see my breakpoints and they seem OK.

FYI I'm running Clojure 1.10.1 and jdk1.8.0_192

[adam-krieg]

I'm still seeing this with Java 11 and latest Cursive. My breakpoints are greyed out. Running with the nREPL with Intellij classpath

[Hendekagon]

I'm still seeing this in the latest Cursive, as soon as I click to create a breakpoint the red dot turns into a greyed out ⌀ with the hover text "No executable code found at line ... in class"

[Magisus]

I just started having the same issue as @Hendekagon after upgrading to Intellij 2021.1.1 and Cursive 1.10.2. I'm using Java 11. A few breakpoints work, but most get greyed out with "No executable code found" and do not trip when running tests from the built-in debug repl, nRepl+leiningen.

Breakpoints in the test file itself seem to work, but the ones in other files, in the code under test, don't seem to most of the time.

also getting "no executable code" on Intellij 2022.1.2, Cursive 1.12.4-2022.1 when trying to set a breakpoint in protocol implementation

~~Any news on this? Ability to debug using breakpoints would really mean a lot...~~

Actually, it turns out the debugger sometimes does stop on the breakpoint which was marked as "no executable code". But it's inconsistend, e.g. it stops on a (println ...) call, but not on (let [...] ...).
