升級3.0之后打開項目報錯，這里記錄一下解決的過程
首先更新了gradle版本
之后報錯
Gradle sync failed: Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=xiaomiDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
Google了一下，是因為項目Gradle下使用的部分代碼語法變了
這是項目中原本自定義構(gòu)建APK的代碼
applicationVariants.all { variant ->
variant.outputs.each { output ->
def newName
def timeNow
def outputFile = output.outputFile
if (Boolean.valueOf(IS_JENKINS)) {
timeNow = JENKINS_TIME
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-" + variant.productFlavors[0].name + "-" + timeNow + "-" + variant.buildType.name + '.apk'
} else {
timeNow = getDate()
if ('debug' == variant.buildType.name) {
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-debug.apk"
} else {
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-" + variant.productFlavors[0].name + "-" + timeNow + "-" + variant.buildType.name + '.apk'
}
}
output.outputFile = new File(outDirectory, newName)
}
}
其中的這句 variant.outputs.each { output ->
需要把each替換成all
獲取輸出文件的代碼output.outputFile已經(jīng)變?yōu)橹蛔x,現(xiàn)在直接使用outputFileName賦值即可修改輸出的名稱
修改后的代碼
applicationVariants.all { variant ->
variant.outputs.all { output ->
def newName
def timeNow
if (Boolean.valueOf(IS_JENKINS)) {
timeNow = JENKINS_TIME
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-" + variant.productFlavors[0].name + "-" + timeNow + "-" + variant.buildType.name + '.apk'
} else {
timeNow = getDate()
if ('debug' == variant.buildType.name) {
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-debug.apk"
} else {
newName = APP_PACKAGE_NAME + "-android-V${defaultConfig.versionName}-" + variant.productFlavors[0].name + "-" + timeNow + "-" + variant.buildType.name + '.apk'
}
}
outputFileName = newName
}
}
修改后 Try Again 繼續(xù)報錯
Gradle sync failed: Cannot choose between the following configurations of project :androidSDK:

- debugRuntimeElements

All of them match the consumer attributes:

看報錯說明是因為依賴的一個model:androidSDK,Google說明新版中依賴項目的語法改變了,依賴包使用舊的語法沒有報錯,
舊版compile project(':androidSDK')
新版implementation project(':androidSDK')
貌似現(xiàn)在依賴包也可以使用implementation
這里還提示一點,gradle文件中:
compile 替換為 implementation
apt 替換為 annotationProcessor
testCompile 替換為 androidTestImplementation
releaseCompile 替換為 releaseImplementation
這里注意一點:compile fileTree(dir: 'libs', include: ['*.jar'])
不需要替換compile,看樣子只有依賴包的時候才需要替換
還有一點,有的依賴包替換成implementation提示找不到,換回compile又可以了
繼續(xù)Tran Again提示需要更新Android SDK Build Tools version 至 26.0.2
之后報錯
Error:android-apt plugin is incompatible with the Android Gradle plugin. Please use 'annotationProcessor' configuration instead.
Error:All flavors must now belong to a named flavor dimension. Learn more at https://d.android.com/r/tools/flavorDimensions-missing-error-message.html
繼續(xù)Google,新版去掉了android-apt,所以刪除項目Gradle中apply plugin: 'android-apt',只保留apply plugin: 'com.android.application'
把apt替換為annotationProcessor
Try Again:
Error:All flavors must now belong to a named flavor dimension. Learn more at https://d.android.com/r/tools/flavorDimensions-missing-error-message.html
根據(jù)官網(wǎng)說法：
you need to first declare one or more dimensions using the flavorDimensions property. After that, assign each flavor to one of the dimensions you declared
必須指定一個或多個 flavor dimensions
flavorDimensions 后面可以添加多個不同類型的參數(shù)例如：flavorDimensions "tier", "minApi"
官方示例:
// Specifies two flavor dimensions.
flavorDimensions "tier", "minApi"
productFlavors {
free {
// Assigns this product flavor to the "tier" flavor dimension. Specifying
// this property is optional if you are using only one dimension.
dimension "tier"
...
}
paid {
dimension "tier"
...
}
minApi23 {
dimension "minApi"
...
}
minApi18 {
dimension "minApi"
...
}
}
項目中原來的代碼:
productFlavors {
_360 {}
xiaomi {}
}
修改后的代碼:
flavorDimensions "default"
productFlavors {
_360 {
dimension "default"
}
xiaomi {
dimension "default"
}
}
繼續(xù)Tran Again:
Error:found unexpected optical bounds (red pixel) on top border at x=102.
Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
Error:Execution failed for task ':ygj_new:merge_360DebugResources'.
> Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
是因為項目.9圖片中含有紅色邊線,刪除即可
繼續(xù)Tran Again:
Error:Execution failed for task ':ygj_new:transformClassesWithAndroidGradleClassShrinkerFor_360Debug'.
> java.lang.ArrayIndexOutOfBoundsException (no error message)
對于這個錯誤真是百思不得其解,研究了兩天在一篇博文的啟示下把Instant Run關(guān)掉,之后就成功了!
