java - 将Symja和log4j-1.2.11添加到Android Studio后，Gradle构建缓慢

Question

我已经试过了:

生成，执行，部署>生成工具> Gradle

并选中Global Gradle设置中的离线工作复选框。

但是，这似乎没有任何区别。

编辑-我刚刚将--stacktrace添加到编译器选项
`

            apply plugin: 'com.android.application'

            android {
                compileSdkVersion 21

                    }
                }
            }

Answer 1

根据这个问题Error:Execution failed for task ':app:dexDebug'，可能是您使用了在Gradle脚本中多次出现的jar文件或lib？

Symjas 2015-09-26开发JAR在JAR内部使用了最新的commons-math 4。这可能与您的commons-math 3依赖项不匹配。

尝试简化为绝对必要的库。

我在最新的android引用应用中使用了以下SymjaDroid libraries:

COMMONS_MATH4_SYMJA.jar
jsr305.jar
log4j-over-slf4j-1.7.2.jar  
slf4j-android-1.6.1-RC1.jar
symja-2015-10-03.jar
