80.7 使用排除创建不可执行的JAR
如果你构建的产物既有可执行的jar和非可执行的jar,那你常常需要为可执行的版本添加额外的配置文件,而这些文件在一个library jar中是不需要的。比如,application.yml
配置文件可能需要从非可执行的JAR中排除。
下面是如何在Maven中实现:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>exec</classifier>
</configuration>
</plugin>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>exec</id>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>exec</classifier>
</configuration>
</execution>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<!-- Need this to ensure application.yml is excluded -->
<forceCreation>true</forceCreation>
<excludes>
<exclude>application.yml</exclude>
</excludes>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
在Gradle中,你可以使用标准任务的DSL(领域特定语言)特性创建一个新的JAR存档,然后在bootRepackage
任务中使用withJarTask
属性添加对它的依赖:
jar {
baseName = 'spring-boot-sample-profile'
version = '0.0.0'
excludes = ['**/application.yml']
}
task('execJar', type:Jar, dependsOn: 'jar') {
baseName = 'spring-boot-sample-profile'
version = '0.0.0'
classifier = 'exec'
from sourceSets.main.output
}
bootRepackage {
withJarTask = tasks['execJar']
}
