如何动态地使用Gradle从aar排除文件？ [英] How to exclude files from aar with Gradle dynamically?

问题描述

pre> apply plugin：'com.android.library'

android {
compileSdkVersion 16
buildToolsVersion25.0.0

defaultConfig {
minSdkVersion 11
targetSdkVersion 16
versionCode 1
versionName1.0

ndk {
abiFilters'armeabi -v7a'
}
}

externalNativeBuild {
ndkBuild {
path'jni / Android.mk'
}
}
$ b $ sourceSets {
main {
manifest.srcFile'AndroidManifest.xml'
java.srcDirs = ['src']
res.srcDirs = ['res']
jni.srcDirs = ['jni']
}
}

packagingOptions {
exclude'/ lib / armeabi-v7a /libv8.cr.so'
排除'/lib/armeabi-v7a/libv8_libbase.cr.so'
// TODO：生成动态ly from`SHARED_V8_LIB_FILENAMES`
}
}


我修改了 Android.mk 文件具有不同的配置，取决于 SHARED_V8_LIB_FILENAMES 环境变量：

  ... 
＃报告配置
 ifeq（$（SHARED_V8_LIB_FILENAMES），）
＃static 
 $（info [Configuration]静态链接到内置的v8）
 else 
＃dynamic 
 
定义info_define 
 $（info [Configuration]动态链接到共享v8库./libfoo-binaries / android_ $（TARGET_ARCH_ABI）/ $ 1）
 endef 
 $（foreach item，$（SHARED_V8_LIB_FILENAMES），$（eval $（call info_define，$（item））））
 endif 
 ... 
  

如何修改我的 build.gradle ，以便根据环境变量 SHARED_V8_LIB_FILENAMES 生成 packageOptions 部分。我需要检查是否设置了变量，使用空格分隔符对其进行解析，并添加文件列表以排除最终 aar 文件。


  apply plugin class =h2_lin>解决方案

：'com.android.library'

android {
compileSdkVersion 16
buildToolsVersion25.0.0

defaultConfig {
minSdkVersion 11
targetSdkVersion 16
versionCode 1
versionName1.0

ndk {
abiFilters'armeabi-v7a'
}
}

externalNativeBuild {
ndkBuild {
path'jni / Android.mk'
}
}

sourceSets {
main {
manifest.srcFile'AndroidManifest.xml'
java.srcDirs = ['src']
res.srcDirs = ['res']
jni.srcDirs = ['jni']
}
}

def sharedV8LibFilesSet = []
def sharedV8LibFile s = System.getenv（'SHARED_V8_LIB_FILENAMES'）
if（sharedV8LibFiles！= null）{
def sharedV8LibFilesArray = sharedV8LibFiles.split（''）
sharedV8LibFilesArray.each {eachFileName - >
sharedV8LibFilesSet.add（** /+ eachFileName）
println[配置]排除共享v8库+ eachFileName +from AAR
}
} else {
println[Configuration]没有从AAR中排除共享v8库
}

packagingOptions {
excludes = sharedV8LibFilesSet
}
}


任何代码样式的变化/改进都会得到满足。

I'm having android library (aar) that contains (and builds while building module) native code:

apply plugin: 'com.android.library'

android {
  compileSdkVersion 16
  buildToolsVersion "25.0.0"

  defaultConfig {
    minSdkVersion 11
    targetSdkVersion 16
    versionCode 1
    versionName "1.0"

    ndk {
      abiFilters 'armeabi-v7a'
    }
  }

  externalNativeBuild {
    ndkBuild {
      path 'jni/Android.mk'
    }
  }

  sourceSets {
    main {
      manifest.srcFile 'AndroidManifest.xml'
      java.srcDirs = ['src']
      res.srcDirs = ['res']
      jni.srcDirs = ['jni']
    }
  }

  packagingOptions {
    exclude '/lib/armeabi-v7a/libv8.cr.so'
    exclude '/lib/armeabi-v7a/libv8_libbase.cr.so'
     // TODO : generate dynamically from `SHARED_V8_LIB_FILENAMES`
  }
}

I've modified Android.mk file to have different config dependent on SHARED_V8_LIB_FILENAMES environment variable:

...
# Report configuration
ifeq ($(SHARED_V8_LIB_FILENAMES),)
# static
$(info [Configuration] Linking statically with built-in v8)
else
# dynamic

define info_define
    $(info [Configuration] Linking dynamically with shared v8 library ./libfoo-binaries/android_$(TARGET_ARCH_ABI)/$1)
endef
$(foreach item,$(SHARED_V8_LIB_FILENAMES),$(eval $(call info_define,$(item))))
endif
...

How can i modify my build.gradle in order to generate packageOptions section dependent on environment variable SHARED_V8_LIB_FILENAMES? I need to check if the variable is set, parse it with space separator and add files list to be excluded from final aar file.

解决方案

Actually i was able to do it myself:

apply plugin: 'com.android.library'

android {
  compileSdkVersion 16
  buildToolsVersion "25.0.0"

  defaultConfig {
    minSdkVersion 11
    targetSdkVersion 16
    versionCode 1
    versionName "1.0"

    ndk {
      abiFilters 'armeabi-v7a'
    }
  }

  externalNativeBuild {
    ndkBuild {
      path 'jni/Android.mk'
    }
  }

  sourceSets {
    main {
      manifest.srcFile 'AndroidManifest.xml'
      java.srcDirs = ['src']
      res.srcDirs = ['res']
      jni.srcDirs = ['jni']
    }
  }

  def sharedV8LibFilesSet = []
  def sharedV8LibFiles = System.getenv('SHARED_V8_LIB_FILENAMES')
  if (sharedV8LibFiles != null) {
    def sharedV8LibFilesArray = sharedV8LibFiles.split(' ')
    sharedV8LibFilesArray.each { eachFileName ->
      sharedV8LibFilesSet.add("**/" + eachFileName)
      println "[Configuration] Excluding shared v8 library " + eachFileName + " from AAR"
    }
  } else {
    println "[Configuration] No shared v8 libraries excluded from AAR"
  }

  packagingOptions {
    excludes = sharedV8LibFilesSet
  }
}

Any code style changes/improvements appreciated.
