kettle问题

jar包下载地址：https://nexus.pentaho.org/#browse/search

kettle仓库地址，两种：

<mirrors>
        <mirror>
            <id>nexus-pentaho</id>
            <mirrorOf>central</mirrorOf>
            <name>Nexus pentaho</name>
            <url>https://nexus.pentaho.org/content/repositories/omni/</url>
        </mirror>
    </mirrors>

<repositories><!-- kettle中央仓库 -->
        <repository><!-- kettle中央仓库 -->
            <id>pentaho-releases</id>
            <name>Kettle</name>
            <!-- <url>https://nexus.pentaho.org/content/groups/omni/</url> -->
            <url>https://nexus.pentaho.org/repository/omni/</url>
        </repository>
</repositories>

问题如下：

java调用.ktr文件时：Plugin type - Unable to list jar files in plugin folder 'C:\Users\YF-0002.kettle\plugins' Caused by: java.lang.NullPointerException

处理方案：

更换commons-vfs2.jar版本

问题如下：

Root Cause
org.apache.jasper.JasperException: Unable to compile class for JSP:

处理方案：

去除kettle中本身依赖与tomcat中冲突的jar，本次冲突jar为jsp-api.jar
处理方式如下

                <dependency>
            <groupId>pentaho-kettle</groupId>
            <artifactId>kettle-engine</artifactId>
            <version>9.1.0.0-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>javax.servlet</groupId>
                    <artifactId>jsp-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

更换commons-vfs2.jar版本
以下搭配的相关jar可正常执行

• kettle-core-9.1.0.0-SNAPSHOT.jar
• kettle-dbdialog-9.1.0.0-SNAPSHOT.jar
• kettle-engine-9.1.0.0-SNAPSHOT.jar
• kettle-ui-swt-9.1.0.0-SNAPSHOT.jar
• metastore-9.1.0.0-SNAPSHOT.jar
• pentaho-vfs-browser-9.1.0.0-SNAPSHOT.jar
• commons-io-1.3.2.jar
• commons-vfs2-2.3.jar
• guava.18.0.jar
