我有这个pom的一个小项目...

在Eclipse中,一切正常,测试正常(使用maven无法找到的类),但是当我尝试通过maven进行全新安装时,出现一个错误,它无法在AbstractCharSequenceAssert
(AssertJ的一部分)中找到这行(这是另一个公共类下面的类):
class UrlParameterStringAssert extends AbstractCharSequenceAssert<UrlParameterStringAssert, String> {
INFO] ---------------------------------------------- ---------------[错误]编译错误:[INFO] ----------------------------------------------- -------------[错误] /home/fschaetz/workspaces/workspace5/.../shipcloud-api/src/test/java/com/example/shipcloud/rest/shipcloud/domain/AddressSearchFieldsTest.java:[103,39]错误:找不到符号[ERROR]符号:类[AbstractCharSequenceAssert
我已经查看了调试输出,并且在运行testCompile时,AssertJ jar实际上位于提供给编译器的类路径上:
-classpath ...:/ home / fschaetz / .m2 / repository / org / assertj / assertj-core / 2.2.0 / assertj-core-2.2.0.jar:...
(该文件存在,可读,包含该类并且在Eclipse中可以正常工作。]
我已经尝试过清理(maven / eclipse),在项目上运行更新等,但是似乎没有任何效果。当我尝试在jenkins,btw中运行Maven安装时,也会发生同样的事情。
麻烦类的导入是...
import static de.assona.rest.shipcloud.domain.UrlParameterStringAssert.assertThat;
import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
import org.assertj.core.api.AbstractCharSequenceAssert;
import org.junit.Before;
import org.junit.Test;
有什么想法吗?
老实说,我不知道为什么是问题所在(并且很高兴为每个人解释这个问题,但是WAS的原因是这两个类在同一文件中定义...
public class AddressSearchFieldsTest {
... some testing ...
}
class UrlParameterStringAssert extends AbstractCharSequenceAssert<UrlParameterStringAssert, String> {
... a custom Assertion class...
}
通常,我不希望这样的事情有麻烦(因为在同一个文件中声明非公共类应该没有问题),但是maven不喜欢它。将UrlParameterStringAssert移至其自己的文件可解决此问题。很想知道为什么。
对我来说,您有一个奇怪的行家设置。
假设我们具有以下结构
src\main\java\Foo.java
src\test\java\sub\optimal\mavenexample\AddressSearchFieldsTest.java
Foo.java
class Foo { }
AddressSearchFieldsTest.java
import org.assertj.core.api.AbstractCharSequenceAssert;
public class AddressSearchFieldsTest { }
class UrlParameterStringAssert extends
AbstractCharSequenceAssert<UrlParameterStringAssert, String> {
UrlParameterStringAssert(String s) {
super(s, UrlParameterStringAssert.class);
}
}
使用pom.xml
跟随目标将由mvn clean compile
执行>
# from the log output maven-compiler-plugin:2.3.2:compile (default-compile)
并生成以下类文件
target\classes\Foo.class
例如,目标
default-testCompile
由mvn clean compile test
执行
# from the log output maven-compiler-plugin:2.3.2:testCompile (default-testCompile)
并生成以下类文件
target\classes\Foo.class target\test-classes\AddressSearchFieldsTest.class target\test-classes\UrlParameterStringAssert.class
您应该检查为什么您的
mvn clean compile
试图编译测试类文件。
