Gradle plugin Jasper jspc to precompile jsps

I'm using the jassper jspc gradle plugin I want to pre-compile all my jsps "on build", the configuration is as notice the documentation:

    buildscript {

        repositories {
            [...]
            maven {
                url "https://cdn.lfrs.sl/repository.liferay.com/nexus/content/groups/public"
            }
        }

        dependencies {
            [...]
"com.liferay.gradle.plugins.jasper.jspc", version: "2.0.1"
        }
    }
    [...]
    apply plugin: "com.liferay.jasper.jspc"

When I execute "gradle task" I can see the plugin tasks were created:

Verification tasks
------------------
check - Runs all checks.
compileJSP - Compile JSP files to check for errors.
test - Runs the unit tests.

But if I luch one of the tasks, for example gradle compileJSP I get the same error:

:project-web:generateJSPJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':project-web:generateJSPJava'.
> Process 'command '/home/[...]/.sdkman/candidates/java/8u121/bin/java'' finished with non-zero exit value 1

Any idea or alternative solution?

Solution

  • Definitively this plugin is not working anymore. In addition nobody is using it (check maven repo use)
