[英]Gradle: Zipping Multi-project dependencies into application JAR file?
In a build.gradle
script, I would perform the following task to include dependencies into a runnable application JAR file. 在
build.gradle
脚本中,我将执行以下任务以将依赖项包含到可运行的应用程序JAR文件中。
jar {
manifest {
attributes(
'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
'Main-Class': 'org.somepackage.MyMainClass'
)
}
from configurations.compile.collect { entry -> zipTree(entry) }
}
However, in multi-project setups I was missing some dependencies in the JAR file. 但是,在多项目设置中,我缺少JAR文件中的某些依赖项。 I ultimately discovered any dependencies specified in other project
build.gradle
scripts were not being included, unless the parent project had those dependencies too. 最终,我发现其他项目
build.gradle
脚本中指定的任何依赖项均未包括在内,除非父项目也具有这些依赖项。
For example, Project A depends on Project B. Project B uses Google Guava. 例如,项目A取决于项目B。项目B使用Google Guava。 When I deployed Project A to a runnable JAR file, Google Guava would not be included and there would be runtime errors.
当我将Project A部署到可运行的JAR文件时,将不会包含Google Guava,并且会出现运行时错误。 If Project A redundantly specified Google Guava in its
build.gradle
script, then it runs just fine. 如果Project A在其
build.gradle
脚本中冗余地指定了Google Guava,则它运行良好。
How can I modify my jar
task above to include dependencies in multi-project setups? 如何修改上面的
jar
任务以在多项目设置中包括依赖项?
I got some ideas from this post that seemed to work. 我从这篇文章中得到了一些可行的想法。
jar {
manifest {
attributes(
'Main-Class': 'com.swa.rm.pricing.reporting.ux.SaleMxReportingUI'
)
}
}
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
