使“gradle javadoc”任务与 Java 9 一起工作

我有一个使用 source/target = 1.9/1.9 的多模块 Gradle Java 项目。有两个模块，my.base and my.dependsOnBase. The my.base模块没有其他依赖项：

module my.base {
    exports my.base.foo;
    exports my.base.bar;
}

The my.dependsOnBase模块只有一个依赖项，即my.base:

module my.dependsOnBase {
    requires my.base;
    exports my.dependsOnBase.baz;
}

当我跑步时$ gradle javadoc它工作得很好my.base。但当它到达my.dependsOnBase我得到以下错误输出：

/path/to/my $ gradle javadoc

> Task :dependsOnBase:javadoc FAILED
/path/to/my/dependsOnBase/src/main/java/module-info.java:26: error: module not found: my.base
    requires my.base;
                     ^
1 error

在项目的早期，我能够进行 Java 编译，它遇到了类似的问题，使用以下方法进行工作：

compileJava {
    inputs.property("moduleName", moduleName)
    doFirst {
        options.compilerArgs = [
                '--module-path', classpath.asPath,
        ]
        classpath = files()
    }
}

但这些属性并不直接适用于 Gradlejavadoc task.

如何让我的 Javadoc 正常工作？

这对我有用

javadoc {
  inputs.property("moduleName", moduleName)
  doFirst {
    options.addStringOption('-module-path', classpath.asPath)
  }
}
