问题
收到通过Bazel编译Java项目时遇到的异常。
BUILD:10:1: //:greeter: 在 'java_library' 规则中没有名为 'src' 的属性
BUILD 文件：
load("@rules_java//java:defs.bzl", "java_binary")
java_binary(
name="ProjectRunner",
srcs = ["src/main/java/com/example/ProjectRunner.java"],
main_class = "com.example.ProjectRunner",
deps = [":greeter"],
)
java_library(
name="greeter",
src=["src/main/java/com/example/Greeting.java"],
)
英文:

问题的原因是在BULID文件中的java_library规则中，属性名称为：srcs而不是src。
load("@rules_java//java:defs.bzl", "java_binary")
java_binary(
name="ProjectRunner",
srcs = ["src/main/java/com/example/ProjectRunner.java"],
main_class = "com.example.ProjectRunner",
deps = [":greeter"],
)
java_library(
name="greeter",
srcs=["src/main/java/com/example/Greeting.java"],
)
编译并且现在正在运行。

英文:
The problem is caused by the fact that the attribute name in the java_library rule in the BULID file is: srcs not src.
load("@rules_java//java:defs.bzl", "java_binary")
java_binary(
name="ProjectRunner",
srcs = ["src/main/java/com/example/ProjectRunner.java"],
main_class = "com.example.ProjectRunner",
deps = [":greeter"],
)
java_library(
name="greeter",
**srcs**=["src/main/java/com/example/Greeting.java"],
)
