testng+maven一些坑

1.

[TestNGContentHandler] [WARN] It is strongly recommended to add "<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"
>" at the top of your file, otherwise TestNG may fail or not work as expected.

需要在testng.xml中添加一行

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="testproj" parallel="false">
    <test name="testDemo1">
        <classes>
            <class name="com.test.demo.SimpleTest.java"></class>
        </classes>
    </test>
</suite>

2.

org.testng.TestNGException: Cannot find class in classpath

原因是testng.xml的用例名称后缀加了.java

<class name="com.test.demo.SimpleTest.java"></class>

3.

报错source1.7不能调用lamber表达式

　　·将maven的settings.xml里面的jdk配置改成1.8的

<profile>
    <id>jdk17</id>
    <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
    </activation>
    <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
			<!-- 文件拷贝时的编码 -->
			<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
			<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
			<!-- 编译时的编码 -->
			<maven.compiler.encoding>UTF-8</maven.compiler.encoding>
		</properties>
</profile>

　　·将eclipse的编码改成jdk1.8的

　　·将eclipse的maven的pom.xml的build-compiler指定jdk版本

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <compilerArgs>
                        <arg>-Xlint:unchecked</arg>
                        <arg>-Xlint:deprecation </arg>
                        <!--<arg>endorseddirs=${endorsed.dir}</arg>-->
                    </compilerArgs>
                </configuration>
            </plugin>

　　

4.

引入了testng的包，但是用着用着就忽然用不了了，红色划线报错。

　　· clean up工程，再maven-update

　　·第一条还不行，就删掉testng的repository，重新maven-update（我就是这么解决的）

5.

.jar which is referenced by the classpath, does not exist.

build path 里面，把relate的那些打叉的包全部remove
