基于eclipse 和maven 本地安装已经安装好

1.将 maven conf/settings.xml整体修改为 <?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <proxies></proxies> <servers></servers> <mirrors></mirrors> <profiles> <profile> <id>pentaho</id> <activation> <activeByDefault>true</activeByDefault> </activation> <repositories> <repository> <id>pentaho-public</id> <name>Pentaho Public</name> <url>http://nexus.pentaho.org/content/groups/omni</url> <releases> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>pentaho-public</id> <name>Pentaho Public</name> <url>http://nexus.pentaho.org/content/groups/omni</url> <releases> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </snapshots> </pluginRepository> </pluginRepositories> </profile> </profiles> <pluginGroups> <pluginGroup>org.pentaho.maven.plugins</pluginGroup> <pluginGroup>com.pentaho.maven.plugins</pluginGroup> <pluginGroup>com.github.spotbugs</pluginGroup> </pluginGroups> </settings> 2.到https://sourceforge.net/projects/pentaho/files/下载对应kettle版本的插件开发样本zip包kettle-sdk-plugin-assembly-8.2.0.0-342.zip a.将zip 解压出来kettle-sdk-plugin-assembly-8.2.0.0-342 b.将kettle-sdk-plugin-assembly-8.2.0.0-342/kettle-sdk-step-plugin通过existing maven projects 方式导入eclipse(下载驱动时间较长) c。Plugin execution not covered by lifecycle configuration: org.pentaho.maven.plugins:license-helper-maven-plugin:1.27:check-licens 解决c问题办法：在pom.xml build标签中添加如下元素 <pluginManagement> <plugins>  <plugin> <groupId>org.eclipse.m2e</groupId> <artifactId>lifecycle-mapping</artifactId> <version>1.0.0</version> <configuration> <lifecycleMappingMetadata> <pluginExecutions> <pluginExecution> <pluginExecutionFilter> <groupId> org.pentaho.maven.plugins </groupId> <artifactId> license-helper-maven-plugin </artifactId> <versionRange>[1.27,)</versionRange> <goals> <goal>check-license</goal> </goals> </pluginExecutionFilter> <action> <ignore></ignore> </action> </pluginExecution> <pluginExecution> <pluginExecutionFilter> <groupId> com.soebes.maven.plugins </groupId> <artifactId> iterator-maven-plugin </artifactId> <versionRange> [0.5.1,) </versionRange> <goals> <goal>iterator</goal> </goals> </pluginExecutionFilter> <action> <ignore></ignore> </action> </pluginExecution> </pluginExecutions> </lifecycleMappingMetadata> </configuration> </plugin> </plugins> </pluginManagement>

使用eclipse 调试kettle8.2源码由于现在是maven管理分成多个小项目尝试第一次将kettle 的ui项目通过existing maven projects 方式导入eclipse 导入后项目名称为: kettle-ui-swt 找到spoon.java 使用run as java application 报错 java.lang.UnsatisfiedLinkError: Could not load SWT library.

解决办法: 到https://sourceforge.net/projects/pentaho/files/Pentaho%208.2/client-tools/下载pdi-ce-8.2.0.0-342.zip（下载最大的1.2GB）解压zip得到data-integration 将安装包data-integration\ui目录下的所有.xul和.properties文件拷贝到源码包…\kettle-ui-swt\src/main/resources\ui目录下即可解决，images文件夹不要复制覆盖

解决办法：在pom.xml中引用此jar包即可解决 <dependency> <groupId>jaxen</groupId> <artifactId>jaxen</artifactId> <version>1.2.0</version> </dependency>

找到spoon.java 使用run as java application 报错 2019/10/31 14:53:38 - General - ERROR (version Unknown, build 0 from 2019/10/31 14:53:31.968 by 26110) : Error starting Spoon shell 2019/10/31 14:53:38 - General - ERROR (version Unknown, build 0 from 2019/10/31 14:53:31.968 by 26110) : java.lang.NullPointerException 2019/10/31 14:53:38 - General - at org.pentaho.di.ui.util.EnvironmentUtils.getUserAgent(EnvironmentUtils.java:86) 2019/10/31 14:53:38 - General - at org.pentaho.di.ui.util.EnvironmentUtils.isUnsupportedBrowserEnvironment(EnvironmentUtils.java:61) 2019/10/31 14:53:38 - General - at org.pentaho.di.ui.spoon.Spoon.checkEnvironment(Spoon.java:9097) 2019/10/31 14:53:38 - General - at org.pentaho.di.ui.spoon.Spoon.start(Spoon.java:9174) 2019/10/31 14:53:38 - General - at org.pentaho.di.ui.spoon.Spoon.main(Spoon.java:707) stopping

解决办法：修改EnvironmentUtils.java类 protected String getUserAgent() { Browser browser; try { browser = new Browser( new Shell(), SWT.NONE ); } catch ( SWTError e ) { log.logError( "Could not open a browser", e ); return ""; } Object userAgentO = browser.evaluate( "return window.navigator.userAgent;" ); String userAgent = null; if(userAgentO != null) { userAgent = userAgentO.toString(); }else { userAgent = null; } browser.close(); return userAgent; } 到现在kettle-ui-swt就可以启动了启动后如何连入插件的源码进行调试开发将 kettle-ui-swt右键 ->build path->configure build path ->java build path->projects->add 将之前导入到eclipse中的kettle-sdk-step-plugin maven 项目添加到kettle-ui-swt项目中 kettle-ui-swt 项目中找到Spoon.java 右键 ->debug as ->debug configurations->arguments->VMArguments添加 -DKETTLE_PLUGIN_CLASSES=org.pentaho.di.sdk.samples.steps.demo.DemoStepMeta ->apply ->debug 至此在打开的ui中的转换-》转换中就可以找到Demo Step 在DemoStepDialog中open方法添加断点便可进行调试
