找不到java Gradle[METAINF/persistence.xml]

Question

我正在使用gradle构建我的JPA/EJB项目，并收到以下警告：

$ gradle jar
:compileJava
Note: Creating static metadata factory ...
Note: The persistence xml file [META-INF/persistence.xml] was not found. NO GENERATION will occur!! Please ensure a persistence xml file is available either from the CLASS_OUTPUT directory [META-INF/persistence.xml] or using the eclipselink.persistencexml property to specify its location. 
2 warnings
:processResources UP-TO-DATE
:classes
:jar

我的项目结构：

   ProjectX
   |-src
   |---main
   |-----java
   |-------domain
   |-------ejb
   |-----resources
   |-------META-INF
   |-----------persistence.xml

有趣的是，坚持。xml最终会出现在目标jar工件中：

$ jar -tf target/projectx.jar
META-INF/
META-INF/MANIFEST.MF
domain/
domain/Employee.class
ejb/
ejb/EmployeeEJB.class
META-INF/persistence.xml

为什么有人抱怨[META-INF/persistence.xml]即使它在那里

gradle文件：

apply plugin: 'java'
project.buildDir = 'target'
sourceSets.all {
    output.resourcesDir = output.classesDir
}
jar{
    destinationDir=project.buildDir
}
repositories {
    mavenCentral()
}
dependencies {
    compile 'org.glassfish:javax.ejb:3.0.1','org.eclipse.persistence:javax.persistence:2.0.0'
}

我现在已经很快用maven进行了测试，没有这样的警告

坚持。xml应该在src/main/resources/META-INF中。这对我很有用。请不要说这是一个非spring项目
