每次我构建我的maven项目并运行应用程序时，都会说

我在/ WEB-INF / lib下添加的所有罐子

这似乎不会发生在战争中通过maven依赖添加的其他罐子。

这是我的pom.xml

<build>
    <outputDirectory>target/${project.artifactId}-${project.version}/WEB-INF/classes</outputDirectory>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <version>3.1</version>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <archiveClasses>true</archiveClasses>
                <webResources>
                    <resource>
                        <directory>${basedir}/src/main/webapp/WEB-INF</directory>
                        <filtering>true</filtering>
                        <targetPath>WEB-INF</targetPath>
                    </resource>
                </webResources>
            </configuration>
        </plugin>
        <plugin>
            <groupId>com.google.appengine</groupId>
            <artifactId>appengine-maven-plugin</artifactId>
            <version>${appengine.target.version}</version>
            <configuration>
                <enableJarClasses>false</enableJarClasses>
                <address>0.0.0.0</address>
                <jvmFlags>
                    <jvmFlag>-Xdebug</jvmFlag>
                    <jvmFlag>-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n</jvmFlag>
                    <jvmFlag>-Ddatastore.backing_store=${project.basedir}\local_db.bin</jvmFlag>
                </jvmFlags>
            </configuration>
        </plugin>
    </plugins>
</build>

再次下载罐子对我没有帮助。我做了几次。请帮助我解决这个问题。

Answer 1

您正在过滤WEB-INF下的所有文件。这包括你的jar文件。

仅过滤那些实际需要它的文件。

Answer 2

除ThorbjørnRavnAndersen外，您还可以指定排除jar文件：

<webResources>
    <resource>
        <directory>${basedir}/src/main/webapp/WEB-INF</directory>
        <filtering>true</filtering>
        <exclude>**/*.jar</exclude>
        <targetPath>WEB-INF</targetPath>
    </resource>
</webResources>

Maven在/ WEB-INF / lib文件夹中构建损坏的jar文件
