Hi,

This question is a sub question from [http://forums.gradle.org/gradle/topics/jacoco-gradle-taskdef-a-class-needed-by-class-org-jacoco-ant-instrumenttask-canno-t-be-found](http://forums.gradle.org/gradle/topics/jacoco-gradle-taskdef-a-class-needed-by-class-org-jacoco-ant-instrumenttask-canno-t-be-found)

The question is, is there a way (config, etc.) to let below code in gradle-launcher-2.2.1.jar start the process with custom -cp?

public DaemonStartupInfo startDaemon()

{

DefaultModuleRegistry registry = new DefaultModuleRegistry();

Set bootstrapClasspath = new LinkedHashSet();

bootstrapClasspath.addAll(registry.getModule(“gradle-launcher”).getImplementationClasspath().getAsFiles());

if (registry.getGradleHome() == null)

{

bootstrapClasspath.addAll(registry.getFullClasspath());

}

if (bootstrapClasspath.isEmpty()) {

throw new IllegalStateException(“Unable to construct a bootstrap classpath when starting the daemon”);

}

new JvmVersionValidator().validate(this.daemonParameters);

List daemonArgs = new ArrayList();

daemonArgs.add(this.daemonParameters.getEffectiveJavaExecutable());

List daemonOpts = this.daemonParameters.getEffectiveJvmArgs();

LOGGER.debug(“Using daemon opts: {}”, daemonOpts);

daemonArgs.addAll(daemonOpts);

daemonArgs.add("-cp");

daemonArgs.add(CollectionUtils.join(File.pathSeparator, bootstrapClasspath));

daemonArgs.add(GradleDaemon.class.getName());

daemonArgs.add(GradleVersion.current().getVersion());

daemonArgs.add(this.daemonDir.getBaseDir().getAbsolutePath());

daemonArgs.add(String.valueOf(this.daemonParameters.getIdleTimeout()));

daemonArgs.add(this.daemonParameters.getUid());

…

}
