Incompatibility with setup-java v4 (Amazon Corretto 21) when using only cli

[teruchi]

Description:

I encountered an issue when using setup-java (with Amazon Corretto 21) together with setup-clojure.

What Works

In a job where I only install clj-kondo and cljstyle to run linters, everything works fine.
Here’s the full step configuration:

- name: Setup java
  uses: actions/setup-java@v4
  with:
    distribution: corretto
    java-version: 21

- name: Install clojure tools
  uses: DeLaGuardo/setup-clojure@13.2
  with:
    clj-kondo: 2023.12.15
    cljstyle: 0.15.0

- name: Clojure lint
  run: |
    cljstyle check --report -v
    clj-kondo --lint src:test

What Fails

In a separate job where I only install the cli tool and try to run tests using kaocha, I get the following error:

/tmp/usr/local/opt/ClojureTools/bin/clojure: line 436: /__t/Java_Corretto_jdk/21.0.7-6.1/x64/bin/java: cannot execute: required file not found

Here is the job step config:

- name: Setup java
  uses: actions/setup-java@v4
  with:
    distribution: corretto
    java-version: 21

- name: Install clojure tools
  uses: DeLaGuardo/setup-clojure@13.2
  with:
    cli: 1.12.0.1488

- name: Clojure test
  run: |
    clojure -M:dev:test

Notes

• Both jobs use actions/setup-java@v4 with the same configuration.
• This issue did not occur before I started using setup-java. Both jobs worked correctly without it.

Hi! Thanks for reporting this.

I made a simple workflow to replicate the problem but it works without problem: https://github.com/DeLaGuardo/setup-clojure/actions/runs/15439686230/job/43454336869
workflow file is here - https://github.com/DeLaGuardo/setup-clojure/actions/runs/15439686230/workflow

Could you check environment variables used for the "Install clojure tools" and "Clojure test" steps? You should see two entries related to Corretto JDK, something like that:

   env:
    JAVA_HOME: /opt/hostedtoolcache/Java_Corretto_jdk/21.0.7-6.1/x64
    JAVA_HOME_21_X64: /opt/hostedtoolcache/Java_Corretto_jdk/21.0.7-6.1/x64

I wonder why there is a /__t/ prefix in the error.

[DeLaGuardo]

most likely you are affected by the same issue
actions/setup-java#840

Thank you.

I debugged it using the setup-java issue you wrote.

It seems that setup-java may not be installing java correctly.

I will look into it some more.
