Gradle - compileJava - remove compile Warnings
提问by Marcel
We use Gradle 2.1 and java plugin. During compileJava different warnings occur, for example:
我们使用 Gradle 2.1 和 java 插件。在 compileJava 期间会出现不同的警告，例如：
warning: [options] bootstrap class path not set in conjunction with -source 1.7
Note: ../SomeClass.java uses or overrides a deprecated API.
We know what they mean but won't fix them (don't ask, other thread :) Is there a way to avoid these messages somehow? They disturb the output a lot:
我们知道它们的意思，但不会修复它们（不要问，其他线程:) 有没有办法以某种方式避免这些消息？它们会严重干扰输出：
:project1:compileJava
warning: [options] bootstrap class path not set in conjunction with -source 1.7
Note: SomeClass.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 warning
:project1:processResources
:project1:classes
:project1:jar
:project2:compileJava
warning: [options] bootstrap class path not set in conjunction with -source 1.7
1 warning
:project2:processResources
:project2:classes
:project2:jar
:project2:war
Isn't is possible for example to redirect the stderr stream during compileJava so that we can grep out the warnings? Or is there another way?
例如，是否可以在 compileJava 期间重定向 stderr 流，以便我们可以 grep 发出警告？或者还有其他方法吗？

try this:
试试这个：
tasks.withType(JavaCompile) {
options.warnings = false
}

Try adding:
尝试添加：
options.compilerArgs += '-Xlint:-deprecation'

No answer posted so far that currently works (Gradle 4.0.1), so here's what does work:
到目前为止还没有发布当前有效的答案（Gradle 4.0.1），所以这里是有效的：
options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
