Gradle file with plugin for copying from plugin

I am creating my first gradle plugin. I am trying to copy a file from the distribution to the directory that I created in the project. Although the file exists inside the jar, I cannot copy it to a directory.

This is my task code:

import org.gradle.api.DefaultTask; import org.gradle.api.tasks.TaskAction; class InitTask extends DefaultTask { File baseDir; private void copyEnvironment(File environments) { String resource = getClass().getResource("/environments/development.properties").getFile(); File input = new File(resource); File output = new File(environments, "development.properties"); try { copyFile(input, output); } catch (IOException e) { e.printStackTrace(); } } void copyFile(File sourceFile, File destFile) { destFile << sourceFile.text } @TaskAction void createDirectories() { logger.info "Creating directory." File environments = new File(baseDir, "environments"); File scripts = new File(baseDir, "scripts"); File drivers = new File(baseDir, "drivers"); [environments, scripts, drivers].each { it.mkdirs(); } copyEnvironment(environments); logger.info "Directory created at '${baseDir.absolutePath}'." } }

And this is the error I get:

 :init java.io.FileNotFoundException: file:/path-to-jar/MyJar.jar!/environments/development.properties (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:120) at groovy.util.CharsetToolkit.<init>(CharsetToolkit.java:69) at org.codehaus.groovy.runtime.DefaultGroovyMethods.newReader(DefaultGroovyMethods.java:15706) at org.codehaus.groovy.runtime.DefaultGroovyMethods.getText(DefaultGroovyMethods.java:14754) at org.codehaus.groovy.runtime.dgm$352.doMethodInvoke(Unknown Source) at org.codehaus.groovy.reflection.GeneratedMetaMethod$Proxy.doMethodInvoke(GeneratedMetaMethod.java:70) at groovy.lang.MetaClassImpl$GetBeanMethodMetaProperty.getProperty(MetaClassImpl.java:3465) at org.codehaus.groovy.runtime.callsite.GetEffectivePojoPropertySite.getProperty(GetEffectivePojoPropertySite.java:61) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGetProperty(AbstractCallSite.java:227) at br.com.smartcoders.migration.tasks.InitTask.copyFile(InitTask.groovy:29)

To emphasize, development.properties is located inside the environment directory inside MyJar.jar

getClass().getResource() returns the URL. To access this URL, you will need to read it directly (for example, using url.text ), and not first convert it to String / File. Or you can use getClass().getResourceAsStream().text , which is probably more accurate. In both cases, you can specify the encoding of the file.
