我在IntelliJ IDEA Ultimate中使用。
我试图导入＆＃39; mysql-connector-java-5.1.46-bin.jar＆＃39;依赖：
1 - 将.jar粘贴到/ libs
2 - 右键单击.jar - ＆gt; ＆＃39;添加为图书馆＆＃39; - ＆GT; ＆＃39;模块库＆＃39; - ＆GT; ＆＃39; OK＆＃39;
这些步骤不起作用，我得到＆＃39;返回代码1用于dex进程＆＃39;错误和唯一没有编译的任务是
Execute task action 5/5 for :app:transformClassesWithDexForDebug
有例外

此try catch块也返回＆＃39;没有为jdbc找到合适的驱动程序：mysql：// localhost：3306 / TestDB＆＃39;
try {
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/TestDB", "root", "");
statement = connection.createStatement();
}
}catch (Exception e){
Log.i("Connection", e.getMessage());
}
这是我的build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "27.0.3"
defaultConfig {
multiDexEnabled true
applicationId "com.example.kalin"
minSdkVersion 20
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support.constraint:constraint-layout:1.1.0'
testCompile 'junit:junit:4.12'
androidTestCompile('com.android.support.test.espresso:espresso-core:3.0.1', {
exclude group: 'com.android.support', module: 'support-annotations'
})
}
另外一些行如multiDexEnabled和applicationId会变灰并说“无法解析符号”
我现在一直在寻找修复约5个小时，尝试制作一个新项目，但似乎没有任何效果。该应用程序工作正常，没有任何jar文件，这使我认为我可能错误地导入它们。
