java - 使用 JUniversal 翻译 Android 项目

Question

我正在使用 JUniversal 将 android 项目的 Java 类转换为 Objective-C 在 Mac OS X (Yosemite) 上安装 J2Objc 并克隆 juniversal 和 jsimple 之后 Link ，当我在终端中运行以下命令时:

./gradlew build install javaToObjectiveC -x test

它显示错误:

:libraries:jsimple-io:javaToObjectiveC FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':libraries:jsimple-io:javaToObjectiveC'. Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin/java'' finished with non-zero exit value 4

• Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

$HOME 目录下的 .bash_profile 文件也被定义:

export ANDROID_HOME=/usr/local/opt/android-sdk
export GRADLE_HOME=/Users/emaar/env/gradle
export M2_HOME=$HOME/env/maven
export JAVA_HOME2=/usr/libexec/java_home
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home
export J2OBJC_HOME=/Users/emaar/env/j2objc
export PATH=$PATH:$M2_HOME/bin:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$GRADLE_HOME/bin:$J2OBJC_HOME:$JAVA_HOME

当我使用时:

$ ./gradlew build install javaToCSharp -x test

它显示 BUILD SUCCESSFUL 没有错误

我也尝试命令:

./gradlew build install javaToObjectiveC -x test --stacktrace

这是 Gradle 问题，下载并设置 Gradle 并在 .bash_profile 上设置 测试后:

gradle -version

得到答案，问题解决。
