Answer 1

あなたのログの行ごとにJavaの8とJMeterの2.11を実行している：につきとして、唯一のバージョン2.12以降

2017/09/14 17:00:16 INFO - jmeter.JMeter: Version 2.11 r1554548

2017/09/14 17:00:16 INFO - jmeter.JMeter: java.version=1.8.0_121

のJMeterは、Java 8と互換性があります

• http://jmeter.apache.org/changes_history.html

参照：

Version 2.12

Now, JMeter 2.12 is compliant with Java 8. Anyway, 2.11 is 5 versions away from 3.2, so very old now.

常にJMeterの最新バージョンを使用してください。

Answer 2

それはJENKINS-37013によって証明だとして、それがエッジの状況を扱うことになると一部のJava開発者が少し緩和されている（または、彼らは単に十分な資格を持っていない）（でもWorkspace Whitespace Replacement Pluginが存在する）

私は再インストールをお勧めしますあなたのJava、ジェンキンスとJMeterのフォルダへのパスにスペースや特殊文字がなく、問題は例えば、離れて行く必要があります。

c:\apps\java 
c:\apps\jenkins 
c:\apps\jmeter 

念のため詳細はContinuous Integration 101: How to Run JMeter With Jenkinsの記事をチェックしてください。
