"Script error" of Groovy script

when run the groovy sample test as follow ` import net.grinder.script.GTest import net.grinder.scriptengine.groovy.junit.GrinderRunner import net.grinder.scriptengine.groovy.junit.annotation.BeforeProcess import net.grinder.scriptengine.groovy.junit.annotation.BeforeThread import net.grinder.util.GrinderUtils import org.junit.Before import org.junit.Test import org.junit.runner.RunWith

import static org.junit.Assert.*

import static net.grinder.script.Grinder.grinder

@RunWith(GrinderRunner) class TestSth{

public static GTest test

// This method is executed once per a process.
@BeforeProcess
public static void beforeClass() {
    test = new GTest(1, "test Thread");
    //test.record(request);
    grinder.logger.info("before process.");
}

// This method is executed once per a thread.
@BeforeThread
public void beforeThread() {
    grinder.statistics.delayReports=true;
    grinder.logger.info("before thread.");
}

@Test
public void test()
{
    String seid="000000000000000000000000000000000000"

    String threadId = GrinderUtils.threadUniqId
    String leftStr = "${threadId}".padLeft(36,seid)
    grinder.logger.info("ThreadId is:"+leftStr)
    assertTrue(true)
}

} `

i get the error from red icon Console is being prepared. Console is started on port 12002 1 agents are starting. 1 agents are ready. All necessary files are being distributed.
