最近新接觸scala代碼的編寫魁蒜、編譯囊扳，使用mvn編譯項目時經(jīng)常碰到“ExecuteException: Process exited with an error: 1 (Exit value: 1)” 。特別是在mvn clean再mvn package時兜看，很容易出現(xiàn)锥咸。
另外，從錯誤日志上看不到具體是哪行代碼編譯有問題细移，找不到原因搏予，很無奈。
最近一次出現(xiàn)該問題是從spark2.1.1中copy了spark-streaming-kafka-0-10_2.11子項目的源碼弧轧，精簡pom.xml之后編譯雪侥，又出現(xiàn)這類問題，詳細(xì)日志如下：

走了許多彎路之后（如修改scala版本號精绎、更換maven-scala-plugin速缨、完全復(fù)制源碼的pom等），最后意外發(fā)現(xiàn)pom中去掉
guava的exclusion就沒問題了捺典。
會報錯的pom:

       <dependency>
           <groupId>org.apache.spark</groupId>
           <artifactId>spark-core_${scala.binary.version}</artifactId>
           <version>2.1.1</version>
           <type>test-jar</type>
           <scope>provided</scope>
           <exclusions>
               <exclusion>
                   <artifactId>guava</artifactId>
                   <groupId>com.google.guava</groupId>
               </exclusion> 
           </exclusions>
       </dependency>

能正常運(yùn)行的pom：

        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-core_${scala.binary.version}</artifactId>
            <version>2.1.1</version>
            <type>test-jar</type>
            <scope>provided</scope> 
        </dependency>

為什么加了exclusion guava就編譯報錯了呢鸟廓，如果是exclusion 其他的artifactId并沒有此問題。spark-streaming-kafka-0-10_2.11源碼中并沒有使用guava的類襟己。

我也暫時沒查出原因引谜，在此提醒遇到類似問題的朋友，多從pom配置而不是代碼入手擎浴，特別注意guava的exclusion很可能會造成此問題员咽。
