自己在使用maven进行package操作时出现 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single (make-assembly) on project hive-udf: Error reading assemblies: No assembly descriptors found. -> [Help 1] 错误。 通过报错信息，应该是maven-assembly-plugin的元素没有指定。 解决方案： 第1步： 把原来的内容：
<plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptors></descriptors> <finalName>hive-udf</finalName> <outputDirectory>${project.build.directory}/../..</outputDirectory> <appendAssemblyId>false</appendAssemblyId> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>修改为
<plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptors>../jar.xml</descriptors> <finalName>hive-udf</finalName> <outputDirectory>${project.build.directory}/../..</outputDirectory> <appendAssemblyId>false</appendAssemblyId> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>第2步：在项目的根目录添加jar.xml
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd"> <id>jar</id> <formats> <format>jar</format> </formats> <includeBaseDirectory>false</includeBaseDirectory> <dependencySets> <dependencySet> <outputDirectory>/</outputDirectory> <useProjectArtifact>true</useProjectArtifact> <unpack>true</unpack> <scope>runtime</scope> <useTransitiveDependencies>false</useTransitiveDependencies> <includes> <include>brucedu.bigdata:*</include> </includes> </dependencySet> </dependencySets> <fileSets> <fileSet> <directory>target/classes</directory> <outputDirectory>/</outputDirectory> </fileSet> </fileSets> </assembly>重新执行package命令，BUILD SUCCESS！
