从Gradle构建中排除临时Realm文件

Question

Realm提供了一个名为"Realm Studio"的数据库查看器,允许用户浏览其数据库的内容.当应用程序用于查看数据库时,它会在数据库目录中创建几个"临时"文件,即:

• 一个.realm.lock文件.
• 一个.realm.note文件.
• 一个.realm.management目录包含:
  • 一个access_control.control.mx文件.
  • 一个access_control.new_commit.cv文件.
  • 一个access_control.pick_writer.cv文件.
  • 一个access_control.write.mx文件.

在Android环境中,通过将数据库放在/assets目录中,有时会将预先存在的Realm数据库与应用程序一起提供.因此,当使用Realm Studio查看此数据库时,将生成上述文件/assets.由于未知原因,这会导致Gradle在:app:generateDebugAssets任务之后无限期挂起,显然是在:app:mergeDebugAssets任务中.

因此,我想找到一种方法从构建中排除这些文件.我尝试了几种方法,例如:

applicationVariants.all { variant ->
    if (variant.buildType.name == 'debug') {
        variant.mergeAssets.doLast {
            delete(fileTree(dir: variant.mergeAssets.outputDir, includes: ['**/*.cv', '**/*.mx', '**/*.lock', '**/*.note']))
        }
    }
}

和其他方法,如:

sourceSets.main.assets.exclude 'appData.realm.management'
sourceSets.main.assets.exclude 'appData.realm.management/access_control.control.mx'
sourceSets.main.assets.exclude 'appData.realm.management/access_control.new_commit.cv'
sourceSets.main.assets.exclude 'appData.realm.management/access_control.pick_writer.cv'
sourceSets.main.assets.exclude 'appData.realm.management/access_control.write.mx'
sourceSets.main.assets.exclude 'appData.realm.lock'
sourceSets.main.assets.exclude 'appData.realm.note'

无济于事.

如何在运行构建时指示Gradle排除这些文件？

Answer 1

我认为问题是你没有删除.realm.management目录.

android {

    ...

    applicationVariants.all { variant ->
        if (variant.buildType.name == 'debug') {
            variant.mergeAssets.doLast {
                delete(fileTree(dir: variant.mergeAssets.outputDir, includes: ['**/.realm.management', '**/*.lock', '**/*.note']))
            }
        }
    }
}

资产目录内容:

apk中的资产目录内容:

猜测你可能正在使用较旧版本的Realm Studio,因为根据问题#842和pull请求#847,这些目录应该同时被正确清理 - 并且还报告,如果没有 - 而不是拖延.当前版本3.12应该已经修复(基本上是6月18日之后的任何版本).如果这不应该有帮助,你可以做的最好的事情是在问题#842下报告; 或提交一个新问题,引用问题#842.还检查文件系统权限,允许运行gradle的用户在那里删除; 手动移动文件"可能"帮助,因此当前用户可以重新创建它们,然后可以删除自己的文件.

使用gradle的两种方法都是变通方法 - 因为它不应该首先发生.

为了获得更多信息"为什么它停止",在终端中运行此命令:

./gradlew -d app:generateDebugAssets

分别在Windows上(问题既不表示OS也不表示Realm Studio版本):

gradlew.bat -d app:generateDebugAssets

编辑:甚至可以在每次构建之前删除这些文件:

task cleanupRealm(type: Delete) {
    delete project.projectDir.path + "/src/main/assets/.realm.management"
    delete project.projectDir.path + "/src/main/assets/appData.realm.lock"
    delete project.projectDir.path + "/src/main/assets/appData.realm.note"
}

tasks.whenTaskAdded { task ->
    if (task.name == "preDebugBuild" || task.name == "preReleaseBuild") {
        task.dependsOn cleanupRealm
    }
}

它将任务图更改为:

:app:checkDebugClasspath
:app:cleanupRealm
:app:preBuild
:app:preDebugBuild

Answer 3

尝试一下：

android {
    aaptOptions {
        ignoreAssetsPattern "!*.cv:!*.mx:!*.lock:!*.note" 
    }
}

从文件夹aapt中的二进制文件build-tools：

./aapt
[...]
--ignore-assets
   Assets to be ignored. Default pattern is:
   !.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~
