关注this Guide我运行了命令
mvn assembly:assembly
并获得了Build Failure
Error reading assemblies: No assembly descriptors found.
我已经看过很多关于这方面的问题,但无济于事。
从this post开始,我在里面创建了一个.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-with-dependencies</id>
<formats>
<format>jar</format>
</formats>
<dependencySets>
<dependencySet>
<scope>runtime</scope>
<unpack>true</unpack>
<unpackOptions>
<excludes>
<exclude>**/LICENSE*</exclude>
<exclude>**/README*</exclude>
</excludes>
</unpackOptions>
</dependencySet>
</dependencySets>
<fileSets>
<fileSet>
<directory>${project.build.outputDirectory}</directory>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
</fileSet>
<fileSet>
<directory>src/main/resources/META-INF/services</directory>
<outputDirectory>META-INF/services</outputDirectory>
</fileSet>
</fileSets>
</assembly>
并将其包含在pom.xml
:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptors>
<descriptor>jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
</plugin>
但仍然没有运气。
我对此很陌生,你可以告诉我,我该如何运行?
~~ EDIT ~~
在pom.xml
我改变了
<descriptor>jar-with-dependencies.xml</descriptor>
要
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
~~编辑2 ~~
pom.xml
现在包含:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
~~编辑3 ~~
此pom.xml
现在对我有用:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
答案 0 :(得分:7)
为此,您需要在jar-with-dependencies.xml
和此XML中创建文件src/main/assembly/
:
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
即。您需要指定文件的路径,惯例是将文件放入src/main/assembly/
。
要使用Maven提供的内容,您需要使用descriptorRef
元素(包含在descriptorRefs
中)。
另外,不要将描述符放在execution
元素内,或者mvn assembly:assembly
再也找不到它(因为你专门将它移到了mvn package
目标)。
[编辑] 我自己也按照教程进行操作,您可能错过了一个重点:您需要选择正确的原型。就我而言,那是5
,但订单可以改变。因此,请阅读整个列表并查找字符串openimaj-quickstart-archetype
,否则事情就会中断。
