maven - 如何在settings.xml中定义maven系统属性？

Question

我正在关注advice from the mvn project使用多个 Artifact 线程进行并行 Artifact 解析。这个命令似乎给了我想要的结果。

mvn -Dmaven.artifact.threads=10 依赖项:resolve-plugins

此 settings.xml 会在每次调用 mvn 时自动设置 maven.artifact.threads 吗？

<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
    <profiles>
        <profile>
            <id>moreDependencyThreads</id>
            <activation>
                <property>
                    <name>maven.artifact.threads</name>
                    <value>10</value>
                </property>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
    </profiles>

    <activeProfiles>
        <activeProfile>moreDependencyThreads</activeProfile>
    </activeProfiles>
</settings>

您可以在 settings.xml 文件中设置此属性，方法如下:

<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
    <profiles>
        <profile>
            <id>moreDependencyThreads</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <maven.artifact.threads>10</maven.artifact.threads>
            </properties>
        </profile>
    </profiles>

    <activeProfiles>
        <activeProfile>moreDependencyThreads</activeProfile>
    </activeProfiles>
</settings>
