我从未使用过 Gradle 的 PMD 插件，并且在尝试将规则集添加到我的项目时遇到了麻烦build.gradle. The Pmd 文档 http://www.gradle.org/docs/current/dsl/org.gradle.api.plugins.quality.Pmd.html不清楚什么是有效值ruleSets是。他们的例子是ruleSets = ["basic", "braces"]他们链接到“官方名单” http://pmd.sourceforge.net/pmd-5.0.5/rules/index.html。不幸的是，没有什么可继续的。
我猜测部分标题以某种方式映射到有效字符串？喜欢，
-
“基本（java）” http://pmd.sourceforge.net/pmd-5.0.5/rules/index.html#Basic->“基本”
-
“大括号（java）” http://pmd.sourceforge.net/pmd-5.0.5/rules/index.html#Braces_java->“大括号”
但是像这样的事情呢？“空代码（java）” http://pmd.sourceforge.net/pmd-5.0.5/rules/index.html#Empty_Code?
这是一个工作build.gradle例子：
apply plugin: 'java'
apply plugin: 'pmd'
pmd {
ruleSets = [
// The first two better work since it's right in the Javadoc...
"basic",
"braces",
// This one does not work and other variations like
// "empty code", "emptycode", "empty-code", "empty_code" do not work.
"emptyCode"
]
}
repositories {
mavenCentral()
}
Gradle 吐出以下错误：
$ gradle check
:pmdMain FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':pmdMain'.
> Can't find resource emptyCode. Make sure the resource is a valid file or URL
or is on the CLASSPATH. Here's the current classpath:
/Users/kuporific/gradle/gradle-1.10/lib/gradle-launcher-1.10.jar
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug
option to get more log output.
BUILD FAILED
Total time: 9.907 secs
跑步与--stacktrace or --debug按照建议似乎没有产生任何有用的东西......
注意：创建一个虚拟文件，例如src/main/java/Dummy.java。否则，构建will成功。
How are ruleSets supposed被宣布？
Edit:
最终声明变得更容易xml规则集，因为它提供了对规则的细粒度控制。它包含在build.gradle像这样：
apply plugin: 'pmd'
pmd {
ruleSetFiles = files('path/to/ruleSet.xml')
}
规则集文件看起来像这样：
注意：此示例是为 Gradle 1.10 编写的。较新版本的 Gradle（大约 2.0）使用较新版本的 PMD；因此，许多rulesets路径改变了。所以rulesets/logging-java.xml现在发现于rulesets/java/logging-java.xml， 例如。
<?xml version="1.0" encoding="UTF-8"?>
