我遇到一个奇怪的问题，当我尝试建立通过我的摇篮project。
当我将项目导入的IntelliJ，并建立通过IDE /运行测试构建工作正常。但是，如果我跑./gradlew test，构建失败，这是无法解决的JDK（如GenericArrayType）符号。
如果我的IntelliJ委托的构建/运行行动摇篮，我看到在我的IDE同样的问题一样，所以有些事情似乎是与我的摇篮建设，我想不出什么。其他项目做工精细，所以它似乎是与此特定项目的问题。
我已经试过这在不同的机器（一个运行Ubuntu和其他运行MacOS之外），以及不同版本的摇篮（4.10.2，5.1.1），但问题仍然存在。我复制并粘贴源代码已经工作完全正常的另一个项目，然后开始与同样的错误失败的为好，当我跑的单元测试。
有人可以帮我找出什么错误吗？
下面是我的settings.gradle的样子：
rootProject.name = 'types'
和build.gradle：
group 'com.vinaysshenoy'
version '1.0.0'
buildscript {
ext.junit_version = '4.12'
ext.assertj_version = '3.11.1'
ext.jsr305_version = '3.0.2'
repositories {
mavenCentral()
}
}
apply plugin: 'java-library'
java {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
repositories {
mavenCentral()
}
dependencies {
implementation "com.google.code.findbugs:jsr305:$jsr305_version"
testImplementation "junit:junit:$junit_version"
testImplementation "org.assertj:assertj-core:$assertj_version"
}
这是我看到的时候我通过命令行运行它：

@ Zgurskyi的回答是一个很好的解决办法，但是，我相信这只是治愈实际问题的症状（见下文）。这里还有一个，要解决根本问题恕我直言，更清洁的方式：使嵌套类型com.vinaysshenoy.types.util.Util的从com.vinaysshenoy.types.Types非静态进口：

（顺便说一句，比@Zgurskyi其他的我也可以用手动javac呼叫重现此我只有一个安装JDK;也许@ Zgurskyi的命令行javac是不是从摇篮使用相同的JDK）
你静态导入嵌套类（不只是类成员），虽然这不应该是必要的。实际上，我惊讶的是，这似乎平时工作，但显然在某些情况下它至少呛一些Java编译器。
在你的情况下，通过使用摇篮Java编译器不能正确解析在以下情况下（只是一个粗略的，不是很技术的编译器做什么说明）进口：
com.vinaysshenoy.types.util.Util时，编译器发现com.vinaysshenoy.types.Types.arrayOf的静态导入，所以编译器着眼于com.vinaysshenoy.types.Types类。com.vinaysshenoy.types.Types有com.vinaysshenoy.types.util.Util.GenericArrayTypeImpl的静态导入，所以编译器会在嵌套GenericArrayTypeImpl类。com.vinaysshenoy.types.util.Util.GenericArrayTypeImpl用途（java.lang.reflect.）GenericArrayType，但是，对于这种类型的进口还没有在这一点上，这导致了“无法找到符号”错误处理。可以说，它也可以被认为是一个JDK错误，这可与某些编译器，但不与他人。
为了建设该项目，用于在com.vinaysshenoy.types.util.Util定义的静态内部类实现的接口完全合格的名称：
public static final class ParameterizedTypeImpl implements java.lang.reflect.ParameterizedType { ... }
public static final class GenericArrayTypeImpl implements java.lang.reflect.GenericArrayType { ... }
public static final class WildcardTypeImpl implements java.lang.reflect.WildcardType { ... }
另外，如果你不想使用完全合格的名称，那么就提取静态嵌套类顶层。
笔记：
javac -cp path_to_jsr305-3.0.2.jar -d bin src/main/java/com/vinaysshenoy/types/Types.java src/main/java/com/vinaysshenoy/types/util/Util.java
我检查了您的项目，并与gradlew clean build能成功地建立它。
我认为gradle这个无法找到JDK安装，因
JAVA_HOME环境变量没有被正确设置（设置并将其指向你的JDK安装目录）。因建项目后，我来完全是另外一个结论：这似乎全系统JDK已损坏的文件 - 并且它与IDE配合工作，这是因为它使用的嵌入式版本。
万一摇篮不能使用JDK，它可以在gradle.properties文件中定义（路径IDE的嵌入式JDK应该工作，比一个安装的系统范围内的，如使用默认越好）：
# replace this path with the path to the IDE's embedded JDK:
org.gradle.java.home = /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home
...这应该已经使它建设。
