我在項目中的以下兩個依賴:使用多個番石榴版本
<dependency>
<groupId>com.google.javascript</groupId>
<artifactId>closure-compiler</artifactId>
<version>v20141215</version>
<exclusions>
<exclusion>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.4.0</version>
</dependency>
正如你可以在依賴關係樹看,它們都包含不同版本的番石榴:
[INFO] --- maven-dependency-plugin:2.1:tree (default-cli) @ extraction ---

衆所周知的問題是番石榴不向後兼容。所以我需要兩種罐子。
錯誤 - 我得到 - 如下:
Error: tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.mapreduce.lib.input.FileInputFormat
這已經在這裏報道:https://issues.apache.org/jira/browse/HADOOP-10961
此外,他們建議用遮光Maven插件來處理它: https://groups.google.com/a/cloudera.org/forum/#!topic/cdh-user/d5_HqUSvVl4
我試過這裏:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.6</source> <!-- If you want to use Java 8, change this to "1.8" -->
<target>1.6</target> <!-- If you want to use Java 8, change this to "1.8" -->
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<relocations>
<relocation>
<pattern>com.google</pattern>
<shadedPattern>project.shaded.com.google</shadedPattern>
</relocation>
</relocations>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
但我仍然得到相同的錯誤。
任何人都可以幫我解決這個Maven問題嗎?
謝謝 菲利克斯
