gradle版本和jdk版本不匹配，升级gradle版本 7.5 以上 |
| Could not find method compile() |
compile替换成implementation； testCompile替换成testImplementation |
| Gradle7以上默认不支持http的maven库 |
maven { allowInsecureProtocol true url ‘http://artifactory.saicm.local/artifactory/maven-virtual/’ } |
| java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not “opens java.lang” to unnamed module @cc43f62 |
添加VM参数 –add-opens java.base/java.lang=ALL-UNNAMED –add-opens java.base/java.util=ALL-UNNAMED |
