javah错误：gradle和Android Studio不存在该程序包

最近在编译Java源代码以产生C ++标头时javah遇到package does not exist错误：为某些文件吐出错误。

tl; dr： javah适用于Java源代码，但不适用于其他Java源代码–哪些import子句非常接近；gradle不会处理某些库，但是即使已处理的程序包也被标记为丢失。

我不知道为什么javah会开始吐出该错误，因为直到最近它都运行良好，并且我没有更改任何特殊内容。我正在使用gradleAndroid Studio的gradle-wrapper。我最近将包装器的发行版从2.2.1更新到2.10，但是我不认为这就是javah现在失败的原因。

根据日志和当前文件，javah在编译时ClassB未从我正在使用的库中找到包，但未找到ClassA。

让我们举两个例子：com.batch.android和com.adjust.sdk

com.batch.android图书馆也得到由gradle这个处理，使得其瓶子是我的build/intermediates/exploded-aar文件夹（在com.batch.android/batch-sdk/1.5.3/jars/classes.jar和com.batch.android/batch-sdk/1.5.3/jars /libs/batch.jar）
com.adjust.sdkgradle无法处理库，因此其jar不在我的build / intermediates / exploded-aar中
两者都在我的〜/ .gradle / cache /文件夹中
这两个软件包都因javah丢失而失败
这两个包都没有进口ClassA和ClassBjava文件

谢谢你的帮助！

好的，它不明白为什么会出现这些错误，但我只是意识到我可以忽略它们，因为C ++头文件仍在生成。

因此，我决定修改javahgradle任务以忽略错误，并将这些错误写入专用的日志文件中。我添加了以下行：

errorOutput = project.file("build/javah_error_${targetName}.log").newDataOutputStream()
ignoreExitValue = true

我的javah任务现在看起来像这样：

['Main', 'Renderer', 'ClassA', 'ClassB'].each {
    def targetName ->
        tasks.create(name: "javahBuild_$targetName", type: Exec) {
            Properties properties = new Properties()
            properties.load(project.rootProject.file('local.properties').newDataInputStream())
            String sdkDir = properties.getProperty('sdk.dir')
            String flavorFolder = getCurrentFlavorFolder()
            errorOutput = project.file("build/javah_error_${targetName}.log").newDataOutputStream()
            ignoreExitValue = true
            commandLine 'javah', '-classpath', "libs/:src/main/java/:$sdkDir/platforms/android-23/android.jar:build/intermediates/classes/$flavorFolder/$config:$sdkDir/platforms/android-23/optional/org.apache.http.legacy.jar/:$config/", '-d', 'src/main/jni/Main/', "my.super.project.${targetName}"
        }
}
