The parameter 'executable' is missing or invalid

[tsmock]

Source repo: https://github.com/tsmock/josm/tree/pom

Notes:

• I'm attempting to convert an ant build.xml file to maven
• I'd like to make it possible to run resource generation and misc scripts with mvn exec:{exec|java}@id
• Two of the tasks are bound to phases and work properly as such. They do not work when called manually.
  • To check the output of those two tasks, look at target/classes/data/projection/custom-epsg -- it should not be empty (and is not empty on mvn clean test-compile or mvn clean package)
  • These tasks are bound to phases that run after compile but before test-compile
• I am probably overlooking something. I'm also probably doing something stupid in the pom files.

Steps to reproduce in cloned repo:

$ git clone https://github.com/tsmock/josm.git --branch pom
$ mvn clean test-compile
$ head -n3 target/classes/data/projection/custom-epsg
$ mvn clean compile exec:exec@epsg-touch exec:exec@epsg
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.2.0:exec (epsg-touch) on project josm-parent: The parameter 'executable' is missing or invalid -> [Help 1]
$ head -n3 target/classes/data/projection/custom-epsg

can you execute your example with:

mvn -X clean compile exec:exec@epsg-touch exec:exec@epsg

and provide output like:

[DEBUG] Configuring mojo execution 'org.codehaus.mojo:exec-maven-plugin:3.2.0:exec:epsg-touch' with basic configurator -->
...
[DEBUG]   (f) classpathScope = runtime
[DEBUG]   (f) executable = java
[DEBUG]   (f) forceJava = false
...
