Gradle - Could not target platform: 'Java SE 8' using tool chain: 'JDK 7 (1.7)'
提问by Vasiliy Vlasov
I am trying to import Gradle project in Intellij Idea with local Gradle distrib and getting stacktrace with the following message: Could not target platform: 'Java SE 8' using tool chain: 'JDK 7 (1.7)'.
Could anyone explain please what could be the reason?

Finally I imported my Gradle project. These are the steps:
最后我导入了我的 Gradle 项目。这些是步骤：
- I switched from local Gradle distrib to Intellij Idea Gradle Wrapper (gradle-2.14).
- I pointed system variable
JAVA_HOMEto JDK 8(it was 7th previously) as I had figured out by experiments that Gradle Wrapper could process the project with JDK 8only. - I deleted previously manually created file gradle.properties(with
org.gradle.java.homevariable) in windows user .gradle directory as, I guessed, it didn't bring any additional value to Gradle.
- 我从本地 Gradle distrib 切换到 Intellij Idea Gradle Wrapper (gradle-2.14)。
- 我将系统变量
JAVA_HOME指向JDK 8（之前是第 7 个），因为我通过实验发现 Gradle Wrapper 只能使用JDK 8处理项目。 - 我删除了之前在 Windows 用户 .gradle 目录中手动创建的文件gradle.properties（带
org.gradle.java.home变量），因为我猜它没有给 Gradle 带来任何额外的价值。

Since I had to compile some source with 7 compatibility, because of some legacy system and ran into the same problem. I found out that in the gradle configuration there where two options set to java 8
由于我不得不编译一些具有 7 兼容性的源代码，因为一些遗留系统并遇到了同样的问题。我发现在 gradle 配置中有两个选项设置为 java 8
sourceCompatibility = 1.8
targetCompatibility = 1.8
switching these to 1.7 solved the problem for me, keeping JAVA_HOME pointing to the installed JDK-7
将这些切换到 1.7 解决了我的问题，保持 JAVA_HOME 指向已安装的 JDK-7
sourceCompatibility = 1.7
targetCompatibility = 1.7

This is what worked for me (Intellij Idea 2018.1.2):
这对我有用（Intellij Idea 2018.1.2）：
1) Navigate to: File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle
1) 导航到：文件 -> 设置 -> 构建、执行、部署 -> 构建工具 -> Gradle
2) Gradle JVM: change to version 1.8
2) Gradle JVM：更改为 1.8 版
3) Re-run the gradle task
3）重新运行gradle任务

you might also have to adding below line in your build.gradle dependencies
您可能还必须在 build.gradle依赖项中添加以下行
compileOnly group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'

I had a very related issue but for higher Java versions:
我有一个非常相关的问题，但对于更高的 Java 版本：
$ ./gradlew clean assemble
... <other normal Gradle output>
Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'.
I noticed that the task succeeded when running using InteliJ. Adding a file (same level as build.gradle) called .java-versionsolved my issue:
我注意到使用 InteliJ 运行时任务成功。添加一个名为 build.gradle 的文件（与 build.gradle 相同）.java-version解决了我的问题：
# .java-version
11.0.3
