zookeeper unit test：quorumPeer never got set - unit-testing

Question

I want to write zookeeper unit test, use embedded zookeeper curator-test.
When my zookeeper version is less than 3.4.0, like 3.3.0, there is no problem.
But when I use the following configuration, there will be problems.
I have searched for many ways to try to solve, but the problem still exists.
maven pom dependencies:
<!--zookeeper-->
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.13</version>
</dependency>
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-recipes</artifactId>
<version>4.0.1</version>
<exclusions>
<exclusion>
<artifactId>curator-client</artifactId>
<groupId>org.apache.curator</groupId>
</exclusion>
</exclusions>

<version>4.2.0</version>
<exclusions>
<exclusion>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</exclusion>
</exclusions>
</dependency>
my unit test code:
public static void main(String[] args) throws Exception {
TestingCluster cluster = new TestingCluster(3);
cluster.start();
Thread.sleep(2000);
TestingZooKeeperServer leader = null;
for(TestingZooKeeperServer zs : cluster.getServers()){
System.out.print(zs.getInstanceSpec().getServerId()+"-");
System.out.print(zs.getQuorumPeer().getServerState()+"-");
System.out.println(zs.getInstanceSpec().getDataDirectory().getAbsolutePath());
if( zs.getQuorumPeer().getServerState().equals( "leading" )){
leader = zs;
}
}
leader.kill();
System.out.println( "--After leader kill:" );
for(TestingZooKeeperServer zs : cluster.getServers()){
System.out.print(zs.getInstanceSpec().getServerId()+"-");
System.out.print(zs.getQuorumPeer().getServerState()+"-");
System.out.println(zs.getInstanceSpec().getDataDirectory().getAbsolutePath());
}
cluster.stop();
}
error & Exception:

I have try:
removing extra zookeeper dependency
version control
But this problem is still not solved, I hope a master can help me point out, thx!!

OMG, I'm so stupid that I didn't expect this to happen
