我正在尝试使用Open Liberty 18.0.0.4为MicroProfile 2.1应用程序构建可运行的jar。我从入门指南中复制了大多数代码，并将版本号从18.0.03更新为18.0.0.4。但是，未构建可运行的Jar，并且在 package-server 步骤中获得了以下输出：

[INFO] Server RepositoryService package complete in /home/thor/workspace/KNIME-trunk/git/knime-repository-service/com.knime.enterprise.cloud.service.repository/target/cloud.service.repository.zip.
关键部分是消息The loose file /home/thor/workspace/KNIME-trunk/git/knime-repository-service/com.knime.enterprise.cloud.service.repository/target/liberty/wlp/usr/servers/RepositoryService/apps/cloud.service.repository.war.xml is invalid.，它似乎破坏了所有内容，因为构建步骤的结果是一个zip文件而不是可运行的Jar。这是它声称无效的文件的内容：
<?xml version="1.0" encoding="UTF-8"?>
<archive>
<dir sourceOnDisk="/home/thor/workspace/KNIME-trunk/git/knime-repository-service/com.knime.enterprise.cloud.service.repository/src/main/webapp" targetInArchive="/"/>
<dir sourceOnDisk="/home/thor/workspace/KNIME-trunk/git/knime-repository-service/com.knime.enterprise.cloud.service.repository/target/classes" targetInArchive="/WEB-INF/classes"/>
<file sourceOnDisk="/home/thor/.m2/repository/com/knime/enterprise/cloud.service.repository.api/0.0.1-SNAPSHOT/cloud.service.repository.api-0.0.1-SNAPSHOT.jar" targetInArchive="/WEB-INF/lib/cloud.service.repository.api-0.0.1-SNAPSHOT.jar"/>

</archive>
我在这里看不到任何无效的东西。另外，如果我在pom.xml中使用18.0.0.3作为assemblyArtifact的版本，则完全相同的过程也可以很好地工作。
