build.gradle报错(eclipse编译不了项目)

大家好，又见面了，我是你们的朋友全栈君。

笔者是通过idea编译spring5源代码，该项目基于gradle构建，编译过程中具体报错如下：

经过上网搜索，很多解决方案给出的都是重命名本地JAVA_HOME/lib下的tools.jar，编译完成之后再恢复原名，笔者尝试之后依旧不能解决问题，

又有一种解决方案是在项目目录下的gradle.properties中配置java home，笔者直接复制java home路径配置，发现还是报如下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Value 'D:Program FilesJavajdk1.8.0_221' given for org.gradle.java.home Gradle property is invalid (Java home supplied is invalid)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

仔细观察发现路劲中的 \ 都不见了，笔者猜想程序是把 \ 当作转义符处理，故将路径中的单斜杠都替换成双斜杠，程序成功编译，配置如下：

version=5.0.17.BUILD-SNAPSHOT
org.gradle.java.home=D:\\Program Files\\Java\\jdk1.8.0_221

配置之后再编译如下
