Question

我没有收到此代码的任何错误。只是我想排除的文件仍然被添加。我正在使用 eclipse

的 maven 插件

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
        <execution>
            <id>only</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>com.Main</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <excludes>
                    <exclude>**/com/uiservices/controllers/*.*      </exclude>
                </excludes>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 1

maven-assembly-plugin 不是这样的。

你想做的是覆盖程序集描述符的配置jar-with-dependencies，这是不可能的。

如果您想做的是创建一个与程序集 jar-with-dependencies 类似的 jar，但没有您自己项目的某些特定类，您必须编写自己的程序集并且在 maven-assembly-plugin 中调用它，如下所示。

src/assembly/jar-with-deps-with-exclude.xml 中的程序集：

<assembly
    xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
    <!-- TODO: a jarjar format would be better -->
    <id>jar-with-dependencies-and-exclude-classes</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <outputDirectory>/</outputDirectory>
            <useProjectArtifact>false</useProjectArtifact>
            <unpack>true</unpack>
            <scope>runtime</scope>
        </dependencySet>
    </dependencySets>
    <fileSets>
        <fileSet>
            <outputDirectory>/</outputDirectory>
            <directory>${project.build.outputDirectory}</directory>
            <excludes>
                <exclude>com/uiservices/controllers/*.*</exclude>
            </excludes>
        </fileSet>
    </fileSets>
</assembly>

这将创建一个程序集，其中没有解压缩的依赖项，并且添加了您的类，排除的除外。

然后在你的 pom.xml 中：

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
        <execution>
            <id>only</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <descriptors>
                    <descriptor>src/assembly/jar-with-deps-with-exclude.xml</descriptor> 
                </descriptors>
            </configuration>
        </execution>
    </executions>
</plugin>

但是如果你需要的是没有排除类的经典jar，你可以直接在maven-jar-plugin中排除它们:

<plugin>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <excludes>
            <exclude>com/uiservices/controllers/*.*</exclude>
        </excludes>
    </configuration>
</plugin>

Answer 2

我遇到了与 maven-assembly-plugin 类似的问题：

项目 beans-conversion 有文件 application.properties， logback.xml，以及 logback.xsd
项目 extract-conversion 也有名为 application.properties、logback.xml 和 logback.xsd
要求 extract-conversion.jar 应包含 beans-conversion.jar 内容，但 extract-conversion.jar 的 application.properties、logback.xml 和 logback.xsd 应覆盖 beans-conversion.jar.

解法：

我们在提取转换的 pom.xml.

中使用 maven-shade-plugin 解决了这个问题，如下所示

...
<dependency>
    <groupId>com.mycompany</groupId> 
    <artifactId>beans-conversion</artifactId> 
    <version>1.0.0-SNAPSHOT</version>
</dependency>

            <includes>
                <include>application.properties</include>
                <include>logback.xml</include>
                <include>logback.xsd</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>

使用 maven-shade-plugin 参考：Maven dependency: exclude one class

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>3.2.1</version>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
        <finalName>${project.artifactId}-jar-with-dependencies</finalName>
         <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> 
              <manifestEntries>
                 <Main-Class>com.taobao.arthas.core.Arthas</Main-Class>
              </manifestEntries>
             </transformer>
            </transformers>
          <filters>
            <filter>
              <artifact>*:termd-core</artifact>
              <excludes>
                <exclude>META-INF/services/io.termd.core.spi.ConfigProvider</exclude>
              </excludes>
            </filter>
          </filters>
        </configuration>
      </execution>
    </executions>
